The Conservatives' report on MP Aidan Burley was published after the conclusion of French legal proceedings against the groom at the "offensive" stag party.
Mark Fournier, for whom Mr Burley acted as best man, was fined 1,500 euros (about £1,200) for wearing an SS uniform and insignia, which is outlawed in France.
A court in Albertville also ordered the 33-year-old to pay 1,000 euros (about £820) to an organisation representing the families of Holocaust victims.
Neither Mr Burley nor any of the other 10 guests at the party were prosecuted.
