Two members of Jeremy Corbyn's cabinet have made public declarations of loyalty and urged their colleagues from splitting the party in an attempt to depose the leadership.

Emily Thornberry said "now is not the time for us to go for a leadership challenge" as she urged colleagues to take a "responsible" view.

"Jeremy was only elected less than a year ago on the back of 60% of the membership voting in his favour," she told BBC1's Sunday Politics.
