Paul Nuttall, Ukip's by-election candidate for Stoke Central, is under investigation after being accused of lying on his nomination form about his permanent address.

The Ukip leader slept on a mattress on the floor at the home he claimed was his permanent residence on Wednesday night, after he was exposed as never having lived there.

In an argument with Channel 4's Michael Crick, the Ukip candidate was forced to admit he hadn't even been to the house, which was previously revealed as being empty of furniture.

This has lead to a police report being filed after claims the candidate has broken election rules, and calls for him to be disqualified.

On his nomination form, Mr Nuttall claimed he lived at the address, but he has admitted that at the time he did not.
