Ilford North MP Wes Streeting has raised questions about whether Prime Minister David Cameron has benefited from his father’s use of offshore funds.

Talking to BBC Radio 4 this morning, Mr Streeting, who is also a member of the Treasury Select Committee, said he was not completely satisfied with Mr Cameron’s assurance his family does not benefit from the funds.

He argued the statement did not clarify whether the Prime Minister used the funds in the past.

Following the publication of the leaked so-called Panama Papers, it was revealed Mr Cameron’s father Ian Cameron was a client of law firm Mossack Fonseca and used the tax haven after he set-up a fund for investors, Blairmore Holdings.

Downing Street was forced to publish a statement yesterday saying the Prime Minister and his family were not benefiting from any off shore funds.

“There are no off shore trusts or funds the Prime Minister, his wife or children will benefit from in the future. It’s put up or shut up time for those questioning his tax affairs,” the statement added.

Mr Streeting said he did not believe politicians should be made accountable for the actions of their family or their political beliefs but he argued Mr Cameron made a “rod for his own back by making a partial statement”.

“The key question is whether or not Mr Cameron benefited from this in the past,” he said.

“The UK and other countries have far more to do to tackle tax havens and if Mr Cameron is serious about tackling this, are we absolutely certain he has no vested interests?” he added.
