Newport (Wales Times) September 16, 2026 — uk/local/newport/">Newport drug dealer Mark Donovan was sentenced at Cardiff Crown Court after police twice found him carrying substantial quantities of crystal meth during a series of investigations spanning approximately 12 months. The 60-year-old admitted multiple offences involving the supply and possession of drugs, including methylamphetamine, GHB, ecstasy, mephedrone and cannabis.

What happened when police first stopped Mark Donovan?

Prosecutor Emily Jermin told Cardiff Crown Court that Donovan was first stopped by police on High Cross Road in Newport on April 21 last year.

Officers seized methamphetamine from Donovan and took possession of his mobile phone. Police also searched his home as part of the investigation. The total amount of crystal meth seized during that stage of the case was 60.379 grams.

The drugs were valued at up to £4,280, according to the information presented to the court. Donovan was subsequently released under investigation while inquiries continued.

The seizure formed part of a wider case concerning alleged drug supply over a period of about 12 months. Investigators later examined information found on Donovan’s phone, including messages relating to the distribution of several controlled substances.

How much crystal meth was found in Cardiff?

On March 10 this year, Donovan was stopped by police on Western Avenue in Cardiff. Officers seized a further 23.9 grams of crystal meth from him.

The second quantity was estimated to be worth £1,680. The incident occurred while the wider investigation into Donovan’s drug-related activities was continuing.

The two seizures together involved more than 84 grams of crystal meth. The prosecution presented the incidents as part of a series of offences rather than as isolated possession matters.

What did police find at Donovan’s home?

Gwent Police later executed a search warrant at Donovan’s home in Rogerstone on April 21 this year.

During the search, officers seized what was described in court as a “range” of drugs. Police also recovered drug paraphernalia, cash and mobile phones.

Analysis of Donovan’s phone produced messages that indicated his involvement in supplying several substances. The drugs identified in those messages included crystal meth, MDMA, GHB and mephedrone, also known as m-cat.

The evidence did not relate only to the crystal meth seizures. It also supported the prosecution case concerning Donovan’s alleged involvement with a wider range of controlled drugs.

What did the phone messages reveal?

Ms Jermin told the court that a drug expert had assessed the value of the drugs referred to in the messages at more than £5,600.

The expert also considered it “highly likely” that further deals had taken place beyond those identified in the messages. That assessment was presented to the court as part of the prosecution’s account of the scale of the alleged supply activity.

The phone evidence was relevant to the charges involving methylamphetamine, GHB, ecstasy and m-cat. It also helped establish the prosecution case that Donovan was concerned in the supply of more than one type of drug.

Which offences did Donovan admit?

Donovan pleaded guilty to a series of offences at Cardiff Crown Court.

The offences included being concerned in offering to supply methylamphetamine and GHB. He also admitted being concerned in the supply of ecstasy and m-cat.

In addition, Donovan pleaded guilty to two offences of possessing methylamphetamine with intent to supply. He also admitted possessing m-cat and cannabis.

The charges covered both possession and supply-related conduct. The possession-with-intent offences concerned crystal meth, while the other charges reflected the wider range of substances identified during the investigation.

What did the court hear about Donovan’s background?

The court heard that Donovan lived at Squires Close in Rogerstone and had three previous convictions.

Gareth Williams, defending, told the court that Donovan had “significant addiction problems”. He said Donovan had made “significant strides” in addressing those problems.

The defence also said Donovan was engaging with the Gwent Drug and Alcohol Service, known as GDAS. The service was supporting him in dealing with his substance-use issues.

Mr Williams said Donovan had stayed out of trouble since 1987. However, he told the court that Donovan had been forced to give up work and had subsequently been “living an isolated lifestyle”.

The barrister also described Donovan as “clearly not a man in good health”. Those submissions were made in mitigation before the judge imposed sentence.

What sentence did the judge impose?

Recorder Caroline Rees KC sentenced Donovan to three years in prison, suspended for three years.

A suspended sentence means the custodial term was imposed by the court but was not immediately activated. Donovan must comply with the requirements and conditions attached to the order during the suspension period. A breach could lead to further action by the court, depending on the circumstances and the applicable terms of the order.

He was also ordered to complete 10 rehabilitation activity requirement days. The requirement is intended to address factors linked to offending and may include structured work designed to reduce the risk of reoffending.

The sentence followed Donovan’s guilty pleas, the nature and scale of the offences, his previous convictions, his personal circumstances and the mitigation presented on his behalf.

Why did the judge refer to Donovan’s addiction?

Recorder Rees acknowledged Donovan’s history of addiction while emphasising the social harm associated with drug dealing.

“You well know, as someone who is addicted to drugs yourself, the damage which dealing drugs does to society,” she told him.

The judge also accepted that Donovan had supplied drugs in order to fund his own addiction. Her remarks recognised the link between his substance-use problems and the offending but did not remove the seriousness of the supply offences.

The sentence therefore combined a suspended custodial term with a rehabilitation requirement. The order placed emphasis on Donovan’s engagement with treatment while retaining the possibility of imprisonment if the suspended sentence is breached.

What support was Donovan receiving?

The defence told the court that Donovan was engaging with GDAS to address his substance issues.

That support was relevant to the mitigation presented at sentencing. Mr Williams said Donovan had made progress in dealing with his addiction and had stayed out of trouble for many years before the offences before the court.

The court nevertheless considered the offending serious enough to warrant a three-year sentence. The custodial term was suspended, alongside the requirement to complete 10 rehabilitation activity requirement days.

The available court account does not state the full terms of any supervision, treatment or other requirements attached to the suspended sentence. It confirms only the three-year suspension and the 10 rehabilitation activity requirement days.

What does the case show about the alleged drug supply?

The prosecution case involved repeated possession of crystal meth, evidence from mobile-phone messages and the discovery of several different drugs at Donovan’s home.

The first seizure involved 60.379 grams of crystal meth, valued at up to £4,280. The second involved 23.9 grams, valued at £1,680. Police also found evidence connected with substances including MDMA, GHB, m-cat and cannabis.

A drug expert estimated that the drugs referred to in the messages could have been worth more than £5,600. The expert’s view that further deals were “highly likely” suggested that the messages may not have represented the full extent of the activity considered by investigators.

Donovan’s guilty pleas covered the offences set out before the court. The sentence was imposed after the judge considered both the seriousness of the offending and the personal circumstances raised by the defence.

Background: what happened in the Donovan case?

The case concerned a series of drug offences involving Mark Donovan, a 60-year-old man from Rogerstone, Newport. Police first stopped him on High Cross Road in Newport on April 21 last year, when officers seized crystal meth and his phone and searched his home.

A later stop on Western Avenue in Cardiff on March 10 led to the seizure of another 23.9 grams of crystal meth. Gwent Police then carried out a search of Donovan’s home on April 21 this year and recovered drugs, cash, paraphernalia and mobile phones.

Phone analysis linked Donovan to messages concerning the supply of crystal meth, MDMA, GHB and m-cat. He pleaded guilty to the offences before Cardiff Crown Court and was sentenced to three years in prison, suspended for three years, with 10 rehabilitation activity requirement days.

The information provided does not identify the South Wales Argus journalist who wrote the original report. It is therefore not possible to give a verified author attribution without risking an incorrect attribution.

Prediction: how could the sentence affect Newport residents?

For Newport residents, the case may increase attention on the availability of crystal meth and other controlled drugs in the area. It also highlights how investigations can combine physical seizures with evidence recovered from mobile phones and searches of residential premises.

The suspended sentence places Donovan under a legal obligation to avoid further offending and comply with the requirements imposed by the court. If he breaches the terms of the order, the court may consider whether the suspended custodial sentence should be activated, subject to the circumstances and applicable legal process.

The rehabilitation requirement and Donovan’s engagement with GDAS may also focus attention on the role of treatment in cases where drug supply is connected to personal addiction. The case does not establish that rehabilitation will prevent future offending, but continued engagement may be relevant to his ability to address the issues identified in mitigation.
