General election 2019: Countdown to campaign as it happened - BBC News
Political parties began setting out their key campaign messages ahead of the general election on 12 December.
The election period may not have officially started, but parties are already getting adverts out to potential supporters on social media.

On Facebook, the Conservatives have started a second geographically targeted campaign, covering 26 constituencies.

It covers a mix of seats where the Tories were a close second in 2017 and those where the party currently have fairly safe majorities.

The Labour Party also has a new campaign promoting an article in the Guardian, alongside the caption: “Boris Johnson’s disastrous Brexit would sell off our NHS to Donald Trump. The NHS says that means skyrocketing costs for life-saving medicines."

The Lib Dems have two new campaigns - one about the changes the party would bring if elected and the other attacking Jeremy Corbyn.

There are nine versions of the advert on Mr Corbyn with a different message on each image.
