Nigel Farage, leader of the UK Independence Party, has said he will be investigating what went wrong, after the party had to suspend a member for a series of what it said were "repellent" postings on social media.
Andre Lampitt, who appeared in a recent party political broadcast for Ukip, made a series of derogatory comments about Islam, Africa and Ed Miliband. Mr Farage told ITV News "this guy should not have got through" the party's selection process for local elections.
But he said the party did not have "a monopoly on stupid people" and that all political parties had to deal with similar difficulties at a local level.
He dismissed the suggestion that the scandal meant the party's campaign was falling apart ahead of the upcoming European and local elections.
