Ed Davey, leader of Britain's Liberal Democrats, says he will put "health and care at the heart" of the campaign during a launch event for the party's general election manifesto in London. The pro-European party also promised to rebuild ties with Brussels after Brexit and rejoin the European single market, although it did not set out a timeline. "In the long term, we need to be back at the heart of Europe, but we're really clear that we're not going to pretend that's going to be easy," said Davey at the launch. The Lib Dems, which were the junior partner to the Tories in a 2010-2015 coalition government, are predicted to become the third-biggest party after the election. IMAGES AND SOUNDBITES
