Sinn Fien
Claim: The Sunday Telegraph suggested five Sinn Fein MPs had claimed a total of almost £500,000 in second home expenses by renting three London properties from the same family "at above the market norm". Both party president Gerry Adams and Northern Ireland Deputy First Minister Martin McGuinness claimed £3,600 per month to rent a shared two-bedroom flat in north London. This was despite the fact the MPs refuse to take up their Commons seats.

Response: Party President Gerry Adams insisted that "no representative of Sinn Fein draws down expenses for self gain". He added: "It's entirely legitimate that we should have rented accommodation in London because we go there to do business on behalf of our constituents and will continue to do that until we have an all Ireland parliament on this island." But he accused other parties of "downright corruption" and called for reform of the system. A Sinn Fein spokesman added that the rent included parking, bills and housekeeping, which ordinary market rents did not. Source:bbc.co.uk/news.

Not bad for someone who didn't go?
