“I know Gerry and Kate will be grateful that the Tory Party has taken swift and appropriate action by ejecting him from the party.

“His actions are not only disgraceful in themselves, they will also cause great hurt to Kate and Gerry. I feel it is appropriate that he now apologises both privately and publicly to them.

“It is a complete disgrace that Madeleine’s name and image should be made fun of in this way.”

Mr Lewis, believed to be in his early 20s and a student at Queen Mary, University of London,- resigned as chairman of Staffordshire CF last month in protest at internal reforms.

Images on the group’s website show him campaigning with David Cameron for last year’s Crewe and Nantwich by-election.

Mr Lewis was not answering his mobile phone yesterday, but most of the exchanges remained visible on his Facebook profile until late yesterday afternoon. Page snapshots showing other comments were featured on the Tory Bear blog.

On New Year’s Day, after the party, Mr Lewis told another CF member, Flick Cox, online: “There was a brief moment when I thought I might have gone too far with elements of the costume, but it was ok.”

He added that another guest at the bash was dressed as Baby P, the toddler who died after a catalogue of horrific abuse.

“There may not be photos, I don’t think anyone wants to risk being associated with them,” Mr Lewis went on.

Ms Cox suggested that he may have “pulled a Prince Harry” – a reference to the royal’s controversial decision to wear a Nazi uniform to a fancy dress party in 2005.

She said she would “hate to have to end our friendship when I become an MP” if he got into trouble over the outfit.

Madeleine McCann went missing while on holiday with her family in Portugal in May 2007. She has yet to be found despite a massive worldwide hunt.
