Kate Hoey has been the Labour MP for Vauxhall in London since 1989. During those thirty years her majority has only dipped below 10,000 once (in 2005). Her majority is currently 20,250 - the highest Labour majority in that seat since it was created in 1950. She won this record majority in 2017, despite being an ardent Brexiteer representing a 78% Remain-voting constituency. That's impressive.
How does her local constituency Labour party (CLP) thank her for three decades of service? By giving her a unanimous vote of no confidence and mocking her on Twitter.
