Cabinet reshuffle: Labour tribute to ex-Welsh Secretary Cheryl Gillan
Cheryl Gillan has confirmed she is to be replaced as Welsh secretary in David Cameron's first major reshuffle since forming his government.
Mrs Gillan said on Twitter it had been a privilege to serve in the cabinet.
There is pressure from Conservatives in Wales for her successor to be an MP with a Welsh seat.
Possible contenders include Wales Office minister David Jones and Stephen Crabb, a whip.
Mrs Gillan, whose constituency is in Buckinghamshire, had been Welsh secretary since 2010.
Owen Smith, Labour's shadow secretary of state for Wales, told BBC Radio Wales she had worked hard for Wales, but that her replacement should be an MP based in Wales.
