Former home secretary Lord Waddington will retire from the House of Lords before the general election, it has been announced.

Lord Waddington, 85, was in Margaret Thatcher's cabinet from 1989 to 1990 as an MP and was then leader of the Lords from 1990 to 1992 before becoming governor of Bermuda.

The Conservative, who stands down from the House on March 26, joins four other peers who are due to retire from the Lords in the coming weeks.

Philosopher Baroness Warnock, 89, an independent crossbench peer, will retire on June 1.

Tory Lord Shaw of Northstead, 94, will retire on March 31 as will crossbencher Lord Tombs, 90, while crossbencher Lord Nickson, 85, leaves on March 27.

Conservative former cabinet minister Lord Jenkin of Roding became the first peer to deliver a valedictory speech before his retirement in January.

Peers have only been able to retire officially since legislation was passed last year and last month Lord Speaker Baroness D'Souza wrote to peers telling them she believed it was a "public duty" for them to retire "at the right time".
