Conor Benn has relinquished his British Board of Control (BBBofC) boxing licence after the governing body announced it had upheld allegations of misconduct.

Benn's scheduled bout with Chris Eubank Jr was postponed earlier this month after it emerged the 26-year-old had tested positive for banned substance clomifene.

The BBBofC subsequently prohibited the fight from taking place, despite promoters from both sides attempting to force a U-turn.

Benn's father, former WBO middleweight and WBC super-middleweight champion Nigel Benn, declared they would "get to the bottom of this" following the fight's postponement, with his son later writing on his Instagram account: "I hope the apology is as loud as the disrespect."

A statement from the BBBofC on Wednesday said: "By a notice dated 17th October 2022, Mr Conor Benn was called by the Board of the BBBofC to attend a hearing to deal with allegations of misconduct pursuant to Rule 25.1.1. The hearing took place on 21st October 2022.

"On the morning of the hearing, Mr Benn voluntarily relinquished his licence with the BBBofC.

"In accordance with its rules and regulations, the Board determined the allegations following the hearing at which Mr Benn was legally represented.

"The allegations against Mr Benn were upheld."
