UKIP leader Nigel Farage has said he will not be standing in the Newark by-election, sparked by disgraced former Tory minister Patrick Mercer's decision to quit over a cash-for-questions scandal.
A 33-year-old man from Nottingham has been arrested on suspicion of assault after Ukip leader Nigel Farage was hit by an egg during a visit to the city.
Nottinghamshire Police say the man remains in police custody at this stage.
Nigel Farage believes efforts to discredit him and his party are failing - and the polls suggest he may well be right.
Almost one third of Britons think that Ukip is a racist party, according to a new ITV News/ComRes poll.
