Jeremy Corbyn has been hit with three quick-fire resignations from his front bench after he sacked two "disloyal" senior figures and promoted a Trident opponent in a so-called "revenge reshuffle".
Jonathan Reynolds, Stephen Doughty and Kevan Jones all quit within the space of 90 minutes, citing differences with the Labour leader on key policy issues and the treatment of their colleagues.
Mr Jones, MP for North Durham, said he "respected" Mr Corbyn's view that Britain's nuclear deterrent should be scrapped, but disagreed and could no longer remain as shadow defence minister.
"I am determined to continue making the case for Labour to have a strong, credible defence and security policies, and I feel that the most effective way for me to continue to do this is from the backbenches," he wrote in a resignation letter.
