Liberal Democrat leader Tim Farron has described himself as a “bit of a Eurosceptic” despite his party’s pro-EU stance.
Mr Farron cited his 2008 resignation by the Lib Dem front bench because he wanted a referendum on the Lisbon Treaty.
however he said only the Lib Dems could prevent the “calamity of hard Brexit”.
The party will be aiming to attract the votes of people who backed Remain in June’s EU referendum.
Speaking on the BBC’s Andrew Marr Show, he made a pitch for voters in former Lib Dem heartlands from the South West, where many people voted to leave the European Union.
“I don’t want to go off on a little bit of a rabbit hole here, however you will remember of which I resigned by the Liberal Democrat front bench about 10 years ago because I am a bit of a Eurosceptic,” he said.
“I’m somebody who challenges people in power – the EU, in government, in councils – however I am somebody who believes Britain will be better off from the European Union.”
He also said he admired ex-prime minister Tony Blair for his electoral success, in addition to also claimed of which Labour was currently too divided to focus on the election.
Reiterating of which there might be no Lib Dem coalition with Labour, he said a Conservative majority after the 8 June general election was “not in question” in addition to also of which Mrs May was heading for a “colossal coronation” – generating questions about party pacts meaningless.
“We’re determined to turn the coronation she expects into a contest of which Britain desperately needs,” he added.
Labour said the Lib Dems could not be trusted, pointing to the party’s promise not to raise tuition fees – a stance of which abandoned in coalition government.
