A Tory MP who attended a stag party where guests dressed as Nazis has been sacked as a Commons aide for "offensive" behaviour and placed under investigation by David Cameron.

Aidan Burley had expressed "deep regret" at the "inappropriate" actions of guests, including toasts to the Third Reich, with whom he partied at a French ski resort.

But he was removed from his post as a parliamentary private secretary (PPS) to Transport Secretary Justine Greening after fresh allegations were made linking him to the behaviour.

The Mail on Sunday, which exposed the party a week ago, said it had new information about the episode.

A Party spokesman said: "Aidan Burley has behaved in a manner which is offensive and foolish.

"That is why he is being removed from his post as Parliamentary Private Secretary at the Department for Transport. In light of information received the Prime Minister has asked for a fuller investigation into the matter to be set up and to report to him."

The Cannock Chase MP issued an "unreserved, wholehearted and fulsome apology" over the party in a letter to the Jewish Chronicle earlier this week.

One of his friends donned a replica SS officer's uniform and another guest reportedly toasted the "ideology and thought processes" of Adolf Hitler's regime.

In the letter he said he wished he had left the stag party.

"What was happening was wrong and I should have completely dissociated myself from it. I had a choice, and I made the wrong choice not to leave. I apologise for this error of judgment."
