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.
ITV News' political editor Tom Bradby is travelling with Nigel Farage and has tweeted the Ukip leader's visit to Swansea has been cancelled due to reports of scuffles in the city centre:
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.
