Boris Becker has been found guilty of four charges under the Insolvency Act relating to his 2017 bankruptcy, a court has ruled.
The three-time Wimbledon champion, who appeared at Southwark Crown Court, has been acquitted of a further 20 counts.
The six-time grand slam winner, 54, was accused of hiding millions of pounds worth of assets, including two Wimbledon trophies, to avoid paying his debts.
Becker was declared bankrupt on June 21, 2017, over an unpaid loan of more than £3 million on his estate in Mallorca, Spain.
The German national, who has lived in the UK since 2012, insisted he had cooperated with trustees tasked with securing his assets, even offering up his wedding ring.
He said he had acted on expert advice.
Jurors found Becker guilty of four charges under the Insolvency Act after a trial at Southwark Crown Court on Friday.
