Central African Republic’s foreign minister has said a reported diplomatic passport for Boris Becker appears to be a fake and the country’s prosecutor general will investigate.

The retired German tennis star claims his role as Central African Republic’s attache to the European Union on sporting, cultural and humanitarian affairs gives him diplomatic immunity from bankruptcy proceedings in Britain.

But the African nation’s foreign minister Charles Armel Doubane, in comments to Radio Ndeke-Luka, rejected the passport that is said to be Becker’s.

Presidential spokesman Albert Yaloke Mokpeme said the head of state never appointed Becker to the post.

The presidency has said: “We are not custodians of the physical and moral integrity of this gentleman.”

Prosecutor general Eric Didier Tambo said officials will investigate.

Becker told the BBC he was given the passport by the country’s ambassador and believed it to be genuine.

“I have a real passport,” he said.

He said he would be “very happy” to visit Central African Republic “and to speak to people personally about how we can move forward and how we can resolve this misunderstanding and this confusion”.
