Jeremy Corbyn has demanded an investigation into the tax affairs of Britons linked to the Panama leaks, including the PM’s family.
The allegations in the Panama Papers have seen David Cameron dragged into a row about his late father’s business affairs.
According to The Guardian, papers leaked from the Panama-based law firm Mossack Fonseca are said to suggest Mr Cameron’s father Ian ran an offshore fund that avoided having to pay tax in Britain by hiring Bahamas residents to sign its paperwork.
Downing Street insists it was a “private matter” whether the Cameron family still had funds in offshore investments.
But while launching Labour’s local elections campaign in Harlow, Essex, Mt Corbyn told reporters: “It’s a private matter in so far as it’s a privately held interest, but it’s not a private matter if tax has not been paid.
“So an investigation must take place, an independent investigation.
“I think the Prime Minister, in his own interest, should tell us exactly what’s been going on.”
The Labour leader said a probe by HM Revenue and Customs should be “about the amount of money of all people that have invested in these shell companies or put money into tax havens”.
He said he also wanted HMRC “to calculate what tax they should have paid over the years”.
Asked whether the PM should resign if he is found to have benefited, he replied: “Let’s take one thing at a time. We need openness, we need an examination, we need a decision after that.”
Pressed about his own taxes, Mr Corbyn said: “There is no problem with my tax affairs, they are very, very limited indeed. I have got an income as an MP, sadly I have got no family trusts of any sort.”
