Sir Ed Davey’s encouraging Parliament to do better at holding public officials to account ahead.

It’s ahead of a Commons vote on Andrew Mountbatten-Windsor later.

The Liberal Democrats want files about the former Prince becoming a trade envoy in 2001 released.

The Kingston and Surbiton MP explains what he wants revealed.

Sir Ed Davey has also apologised for his historic support for Andrew as trade envoy, saying he did not know what he does now.

He previously said when in the coalition Government in 2012 that he believed “the Duke of York does an excellent job as the UK’s Special Representative for International Trade and Investment.”
