Boris Becker was found guilty of four charges under the insolvency act.

The former world number one was accused of hiding assets to avoid paying his debts.

He was declared bankrupt in June of last year due to an outstanding loan of more than three million dollars.

Becker was acquitted of a further 20 charges on Friday.

He was found not guilty of failing to hand over the Wimbledon men's singles trophy and other tennis medals.

The six-time Grand Slam champion wouldn't be commenting on the verdict.

He was found guilty of transferring hundreds of thousands of pounds from his business account after his bankruptcy, failing to declare a property in Germany, and concealing 825,000 of debt.

He could be sentenced to seven years in jail for each count.

Becker told the jury his career earnings were spent on an expensive divorce from his first wife in 2001, child maintenance payments, and expensive lifestyle commitments.

The former tennis star told the court that he was shocked and embarrassed when he was declared bankrupt, and that he had co-operated with those tasked with securing his assets.

Becker, a German national who has lived in the UK since 2012 was cleared of failing to declare a second German property, as well as his interest in a 2.5 million dollar flat in London.

He said during the trial that he earned a lot in his career, but his income plummeted after he retired.

He was too trusting and reliant on his advisers, according to his barrister.

The jury was told to ignore Becker at the start of the trial.

She said that you should treat him the same way you would treat someone who is not in the public eye.

The chief executive of the Insolvency Service said that the conviction serves as a clear warning to those who think they can hide their assets. You will be found out and prosecuted.

Becker will be sentenced on 29 April.
