French prosecutors announced on Wednesday that they had opened a formal investigation into a Nazi-themed stag party. A British MP who attended it lost his parliamentary job as a result.
Aidan Burley was sacked as Parliamentary Private Secretary to Transport Secretary Justine Greening after it emerged that a guest wore SS uniform at the ski-resort party in Val Thorens late last year, while others allegedly toasted the Third Reich.
Conservative Party headquarters said that its own inquiry would be published by the end of the month.
Mr Burley apologised but ran into trouble again this week after being accused of being disrespectful during a Holocaust survivor's testimony.
