West Ham MP Lyn Brown has issued a statement explaining her design to resign as shadow minister last week.

She said she had stood down “with great sadness and a strong feeling of regret” after tendering her resignation as a shadow Home Office minister.

She said: “I was pleased to have the opportunity to serve in Jeremy’s {Corbyn] team. I have enormous respect for him as a person and as a tireless campaigner for the causes we both believe in.

“Following the overwhelming vote of the parliamentary Labour party, it was with a heavy heart that I concluded that we had reached a tipping point and, for the good of the party and the country, I believe that we should seek a new leader.

I will continue to do my utmost to campaign for the Labour party that I love and for my constituents in West Ham from the backbenches.”

Ms Brown had been a shadow home office minister since September and resigned after the party’s MPs took a vote of no confidence last Tuesday.
