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.
Protesters have been pictured gathering in Swansea city centre ahead of Nigel Farage's planned walkaround - which has now been cancelled amid reports of scuffles.
Channel 4 News correspondent Andy Davies reports that Nigel Farage is now heading straight to the Liberty's Stadium to avoid the scenes.
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.
