Nigel Dodds, Deputy Leader of the Democratic Unionist Party, has said he thinks it was wrong that his party was "excluded" from tonight's live leaders' debate.
Speaking to ITV News, he said:
Last night there wasn't one particular knockout blow but the political landscape in Britain does seem to be shifting.
Another day on the election trail and the campaign catchphrase is starting to bite.
Leaders' Debate shows was how our political horizon has suddenly changed as smaller parties did all they could to make themselves heard.
