With British voters going to the polls on June 8, the big parties did not want to waste any time ahead of the official launches of their election manifestos.
She said the Conservatives would provide "strong and stable leadership" for Brexit and beyond, and promising to wage "a positive and optimistic campaign".

Mr Corbyn has insisted he will not go into coalition with the Scottish National Party, despite Nicola Sturgeon's offer of a "progressive alliance" with Labour and the Lib Dems to keep the Conservatives from power.

Liberal Democrat leader Tim Farron said that, for May, calling the election is "the political equivalent of taking candy from a baby".
"Instead of the country's wealth being hidden in tax havens, we will put it in the hand of the people", he said.
