Heard a piece on Newstalk this morning where the prospect of Johnson losing his seat was considered. Whilst deemed unlikely by the British pundit, the idea that it is even being considered - on Irish media - suggests that as a prospect it is being considered in British media too.
Its signals like this, along with reports of significant increase in voter registration and a return to traditional tribal bases that make me think that this will be a close call, in terms of whether or not the Tories secure a majority.
