Greater Manchester Mayor Andy Burnham says he is concerned about the "balance" of the cabinet after a reshuffle sparked by Angela Rayner's resignation for under paying stamp duty.
She left her roles as housing secretary and deputy prime minister, as well as deputy leader of the Labour Party, the latter of which has triggered a contest to find her replacement.
Burnham told Sunday with Laura Kuenssberg that process would be an opportunity to have a "discussion about the internal management" of the party and that somebody from the north of England would be "great".
Defence Secretary John Healey said there was a "good new team in place" and called on them to "go up a gear".
