Former Tory MP Mercer resigns after Commons suspension

A former Tory MP has resigned after he was suspended from the Commons for six months for allegedly asking questions in Parliament in return for money.

Patrick Mercer said he was "ashamed" and had decided to "fess up" by standing down straightaway.

This will trigger a by-election in his Newark constituency in Nottinghamshire, which he has represented since 2001.
