Labour dismissed accusations they had failed to capitalise on voters' disillusionment with the Government at the European and council elections, dubbing their wins "a very good set of results".
Shadow Business Secretary Chuka Umunna told Good Morning Britain Labour had won "over 25% of the vote", a growth of 9% on the last round of European elections.
"We have seen our tally of MEPs go up from 13 to 18. We're expecting to get another couple on top of that. So that is a really good set of results on top of a good showing in the local elections."
