Baroness Williams has delivered her final speech to the House of Lords before retiring from the chamber.

In her speech she talked of the UK's "special genius" for "great public sector imagination" and international leadership.

The former education secretary said she hoped the UK would continue to play that leadership role by staying within the European Union.

Once tipped to be the UK's first woman prime minister, the then Shirley Williams was one of the Gang of Four Labour MPs who quit to form the Social Democratic Party in the early 1980s that changed the political landscape.
