Former Labour minister Denis MacShane has resigned after being suspended from the Commons for fiddling his expenses.
Chancellor George Osborne has appointed Mr MacShane to the post of Steward and Bailiff of the Three Hundreds of Chiltern.
The appointment is the technical procedure enabling MPs to resign their seat in the Commons.
Labour leader Ed Miliband said he was "right" to step down from Parliament after being condemned for abusing expenses rules.
