Neil Parish, the MP for Tiverton and Honiton, has resigned after admitting he watched pornography twice in the House of Commons. He said it had been a ‘moment of madness: I was not proud of what I was doing’. The first time was accidental after he looked at a tractor website, but the second time was deliberate. Mr Parish appeared emotional as he announced he was standing down after seeing the furore and damage it was causing his family and his constituency. This will trigger a by-election in what is a safe Tory seat. But this story - and others - have damaged Parliament's reputation, and the Conservative Party. Both will be hoping that Mr Parish's resignation will help them start to move on.
