British Prime Minister David Cameron has admitted he held a 30,000 pound (A$56,000) stake in an offshore fund set up by his late father, after days of pressure following publication of the Panama Papers.

Mr Cameron said he sold the stake in the Bahamas-based trust in 2010, four months before he became Prime Minister, in an interview with television channel ITV.

Downing Street issued four statements on the affair this week after the publication of the leaked Panama Papers, which showed how Panama-based law firm Mossack Fonseca had helped firms and wealthy individuals set up offshore companies.

“We owned 5,000 units in Blairmore Investment Trust, which we sold in January 2010. That was worth something like 30,000 pounds,” Mr Cameron said.

“I sold them all in 2010, because if I was going to become Prime Minister I didn’t want anyone to say you have other agendas, vested interests.”

Mr Cameron said he paid all UK taxes on the profits and insists he has nothing to hide, adding his father’s investment fund was not set up to avoid British taxes.

“I’ve never hidden the fact I’m a very lucky person. I had wealthy parents,” he said.

A spokesman for Mr Cameron said neither the Prime Minister, his wife nor their children would benefit in future from any offshore funds or trusts.

He had initially described the holdings of his late father, Ian, as a private matter, adding he and his family did not benefit from any such funds at present.
