The three times Wimbledon champion Boris Becker has denied hiding assets including a Chelsea flat and £1.2m in cash from bankruptcy trustees, in a prosecution that could lead to seven years in jail. The German former tennis star, who was declared bankrupt in June 2017, appeared in Westminster magistrates’ court accused of failing to comply with a legal obligation to disclose financial information. Arriving in court wearing a black face mask bearing the logo Stronger Together, Becker denied 19 charges of alleged concealment. The court heard that he owned a flat in Coleherne Court in Chelsea, London, as well as two properties in Germany, which went undeclared between June and October 2017. He also concealed debt worth £754,190 and a bank account holding £1.2m, plus 75,000 shares in the AI firm Breaking Data Corp, the court was told. His lawyer, Jonathan Caplan, said: “These charges will be vigorously contested.” Becker, 52, denied seven charges of concealing property, four counts of omitting statements relating to bank accounts with JP Morgan Belgium and Julius Baer Guernsey, two counts of removing property required by the receiver, five counts of failing to disclose details of his estate and one count of concealing debt. If he is convicted he faces a prison sentence of up to seven years. The chief magistrate, Emma Arbuthnot, committed his case to Southwark crown court where he faces a plea and trial preparation hearing on 22 October. Caplan asked for Becker’s address not to be disclosed in court. Arbuthnot rejected the request. She said: “Every well known celebrity who’s gone through here has to do it. You have to argue it properly if you want to do that.” Caplan described his client as an “international celebrity”, adding: “All the Grand Slam championships mean he travels frequently.” The court heard Becker plans to fly to Munich next week and has been staying at a luxury penthouse in Montevetro, Battersea in south-west London. Becker was released on conditional bail with requirements to live and sleep at the Battersea property and notify the Insolvency Service, which is prosecuting the case, two days before travelling abroad. Becker burst on to the tennis scene in 1985, when he became the youngest Wimbledon men’s singles champion at the age of 17 years and seven months. He was the first German champion of the tournament and the first non-seed to win as he was ranked at number 20. The former world No 1 and six-time Grand Slam champion collected 49 singles titles out of 77 finals during his 16 years as a professional tennis player. He was chosen to enter the International Tennis Hall of Fame in 2003 and appears regularly as an expert summariser and commentator on the BBC.
