Introduction

The MP for Dover, Natalie Elphicke, has shocked MPs and pundits across the political spectrum by defecting to the Labour party today. In her resignation letter, she accused the Conservative party for having 'abandoned' the 'centre ground'. But for someone who has vocally criticised Labour in the past, how helpful is Elphicke's defection? Oscar Edmondson talks to Katy Balls and Isabel Hardman.
