Michael Dugher has been appointed shadow minister for the Cabinet Office as part of a reshuffle by the Labour leader Ed Miliband.
The MP for Barnsley East replaces Jon Trickett, who has swapped roles with Dugher to become shadow minister without portfolio and remains part of the shadow cabinet.
Trickett, who was in post for exactly two years, will also be deputy party chair.
Dugher, who entered parliament in 2010, is a former chief political spokesman for the then Prime Minister Gordon Brown and has been vice-chair of the Labour Party since November 2012.
He was parliamentary private secretary to Miliband between May and October 2011, and was also shadow minister for defence equipment, support and technology between October 2010 and September 2011.
He worked as a special adviser under the last Labour government in areas including transport, local government and defence.
Dugher’s website says he is a "national champion" for Save the Children, works closely with the British Heart Foundation as vice-chair of the All-Party Parliamentary Group on Heart Disease, and is a member of the Royal British Legion’s Hoyland and District branch.
