Party leaders hit the campaign trail

Available for over a year

On the first full day of campaigning for the general election - party leaders have been road-testing their slogans. On a day of claims and counter-claims about immigration - we do some fact-checking - and reflect on the campaign with our political editor. Also on the programme: A rare report from inside military-controlled Myanmar - on the human cost of the rebel insurgency. And, at the Chelsea Flower Show, a garden that helps torture victims cope with their trauma.
