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.
