Jeremy Corbyn campaigns against Brexit

Jeremy Corbyn insisted there was “nothing half-hearted” about Labour’s pro-EU campaign as he made his first major speech of the referendum battle.

The Labour leader — who voted Out in the 1975 referendum and has expressed Eurosceptic views over subsequent decades — has been accused of making only a lukewarm contribution to the Remain argument so far.

However, he said it was clear that his party was “overwhelmingly convinced” that being part of the EU was in the best interests of the country on issues such as workers’ rights and the environment.
