Workington MP Sue Hayman has joined the Labour frontbench.
Mrs Hayman was approached by chief whip Rosie Winterton to become an opposition whip in the shadow cabinet.
Details have yet to be finalised, but it is likely she will be attached to two teams of shadow ministers and will be responsible for a region of MPs, allowing them time off and marshalling them for votes in the House of Commons.
She will join a team of 12 Labour whips in the House of Commons, seven of whom were elected for the first time in May.
Mrs Hayman said: "
"I look forward to the task ahead of me and taking the fight to the Government on so many important issues in the House of Commons.
"I can't wait to get down to work when Parliament returns from recess on October 12.”
