David Cameron will personally decide the fate of Cannock Chase MP Aidan Burley, once an inquiry into the Nazi-themed stag party attended by the MP reports its findings this month.

Conservative officials are continuing to investigate claims that Mr Burley was involved in preparations for the party at a French ski resort.

The MP for Cannock Chase, aged 32, has already been sacked as a parliamentary private secretary to the Transport Secretary, Justine Greening, after it was reported he had hired a replica SS uniform worn by the groom.

Downing Street initially refused to take any action against Mr Burley, after the MP admitted attending the party where revellers toasted the Third Reich and the groom gave Nazi salutes but initially appeared to suggest he had not known what to expect before he got there.

Reports that he had in fact hired the costume worn by the groom, Mark Fournier, led to him losing his post as a Ministerial aide, and to Mr Cameron ordering an inquiry.

In theory, the Tory leader could strip Mr Burley of the party whip, expelling him from the Conservative group in the House of Commons.

But the party leader does not have the power to deselect candidates.

Conservative officials said the investigation was continuing and the party would not comment until it had been concluded. But an official did confirm that Mr Cameron would be presented with the findings and would decide what action, if any, should be taken.

The MP has returned to the spotlight following a period of silence by launching a new campaign to stop union officials carrying put union duties while they are being paid from public funds.

He chairs the Trade Union Reform Campaign, which launched in the House of Commons last month.
