In court documents seen by the BBC, prosecutor Sam Ponniah told jurors police found messages between the defendant and Christopher and Jonathan McAllister – who were jailed in 2022 for importing Class A drugs – after authorities infiltrated Encrochat servers in 2019.

The messages were exchanged between March and May of 2020 and revealed Bulcroft to be part of a conspiracy to supply cocaine, he said.

“There are conversations where Yummycub speaks to the McAllisters, or an associate of them, and is enquiring about buying kilos of cocaine at around £38,000 a go,” Mr Poniah told the court.

“Naturally the police wanted to work out who Yummycub was because clearly they were involved in buying significant amounts of drugs directly from importers.”

Bulcroft, who once shared the ring with Amir Khan, was also referred to as ‘The Boxer’ by the McAllisters, the court heard.

He asked one of them to meet him at “the gym” which shared the same postcode as his former boxing gym in Denaby Main, as well as “my house”, a location which matched his then home address.

He also replied “Thank You” to a happy birthday message on 10 May 2020 – the date of his birthday – which Mr Poniah said made it “crystal clear” he was Yummycub.
