The Labour leader Sir Keir Starmer said that the resignation of Jennie Formby, the party’s general secretary resigned by “mutual agreement.”
Fromby was a close ally of the former Labour leader Jeremy Corbyn, and on Monday she announced she is to quit.
Sir Kier told BBC Radio 4’s Today programme: “It was a mutual agreement and I wish her the very best.
“We need to move on as a party. Put a new team in place to face the future.”
Formby insisted now is the “right time” to quit whist Sir Kier takes hold of the party.
