Boris Becker has  reportedly been offering Wimbledon “commentary” for fellow inmates during the tennis fortnight from inside his low-security Oxfordshire prison.

London’s Daily Star said the six-time Grand Slam champion who is serving a term for bankruptcy fraud, has become a man in demand, with other inmates persuading him to explain the game and make expert predictions during BBC telecasts.

So far, the tabloid reports, the 54-year-old who served as a BBC colour commentator for nearly two decades has been spot-on with his foresights.

He reportedly correctly called the early exits of British hopes Andy Murray and Emma Raducanu this first week and is tipping Novak Djokovic and Rafael Nadal to be in the thick of the title fight in a week.

The tab quoted a source: “When Boris is on a roll it’s just like listening to the BBC. 

“At first, he was very quiet [and] minding his own business, then a couple of inmates asked him to explain a few of the rules and it all took off. 

“Now everyone gathers around Boris when they are watching matches, either in his cell or on one of the main TVs.

“He has explained and demonstrated how to serve, what top spin is and how to do a drop shot. It certainly makes the time go a little bit more quickly.”
