FULL disclosure is needed over the scandals of Peter Mandelson and Andrew Mountbatten-Windsor’s links to paedophile financier Jeffrey Epstein if trust in politics is ever to be restored, MPs are urging.

After Mr Mandelson’s arrest on suspicion of misconduct in public office, following that of Mr Mountbatten-Windsor last week, such a probe is vital, they said.

Mr Mandelson is understood to deny any allegation of criminality.

Left MP Bell Ribeiro-Addy accused Prime Minister Sir Keir Starmer of “issues of poor judgment” which were damaging politics more generally.

“We need to get to a point now of maximum accountability,” she said. “There should be a wide-ranging investigation into all these things.

“The major issue has been the damage of trust between us and the British public, and they need to feel that something’s being done about it.”

Liberal Democrat leader Sir Ed Davey said all documents relating to Mr Mountbatten-Windsor’s appointment as British trade envoy should be published.

It is believed that Mr Mandelson lobbied hard for his appointment at the time, overcoming reservations by the then Prince of Wales, now King Charles.

“Alarmingly we have read that Peter Mandelson wrote to the then prime minister Tony Blair as his former trade secretary, pushing for Andrew’s appointment,” Sir Ed said.

“One friend of Epstein lobbying for a job for another friend of Epstein, a job that might help Epstein enrich himself. So we clearly need to get to the bottom of that appointment and the role Mandelson himself played in it.”

The government has already promised to release documents relating to Mr Mandelson’s appointment as ambassador to Washington, an epic misjudgement by Sir Keir which has come close to ending his premiership and has brought down his powerful chief of staff Morgan McSweeney.

MPs likewise agreed today to secure the publication of documents relating to Mr Mountbatten-Windsor’s appointment.

Trade Minister Sir Chris Bryant told the Commons that the former prince was “on a constant self-aggrandising, self-enriching hustle.”

He was “a rude, arrogant and entitled man who could not distinguish between the public interest which he said he served, and his own private interest,” Sir Chris said.

“Sometimes it feels to many members of our country that there is one rule for the rich and famous and there is one rule for the rest of us. But actually there is only one rule, the rule of law.”

However, release of the documents in both cases is being delayed by fears of prejudicing the police investigations. Scotland Yard is vetoing publication of some material.
