A Yorkshire MP's own social media feed was used by a member of his team to resign, using a tirade of abuse in a number of messages.

The account credited to Jared O'Mara was apparently taken over by his Communications Manager, who challenged the Sheffield Hallam MP to resign and call a by-election.

Mr O'Mara is seen as a controversial figure by some: he was suspended by Labour over social media comments, and later resigned to become an Independent. He has been accused of neglecting constituents but has openly talked about mental health issues.
