The link between these people:

Brian Faulkner (1922-1977), ex-Prime Minister of Northern Ireland
Betty Harvie Anderson (1913-1979), ex-Deputy Speaker of the House of Commons
Walter Monslow (1895-1966), ex-Labour MP
Stephen King-Hall (1893-1966), sailor, writer and ex-Independent MP
Benjamin Britten (1913-1976), composer
Tom Driberg (1905-1976), ex-MP (and supposedly KGB agent)
Nicholas Ridley (1929-1993), ex-Conservative minister
Joan Lestor (1931-1998), ex-Labour MP
Frederick Erroll (1914-2000), ex-Conservative minister (this one arguable)
James Chuter Ede (1882-1965), ex-Labour minister

is that all of them died less than a year after getting a life peerage.

I should have realised that David Boothroyd had already compiled this list at the end of this very long page.

Congrats to who worked it out.

Erroll is a marginal case because he had been given a hereditary peerage in 1964, got kicked out with the other hereditary peers and was then allowed back in again because he was a former cabinet minister who would have had a life peerage if they’d been more usual in 1964.

For hereditary peers, I learn that:

Wilfred Carlyle Stamp, 2nd Baron Stamp, was killed in a German air-raid on London on 16 Apr 1941. His father, the 1st Baron, was killed by the same bomb. However, it was assumed that the son had died after the father, even by a split-second, and on that basis the 2nd Baron was held to have succeeded to the title… Charles Brandon, 3rd Duke of Suffolk succeeded to the title on the death of his brother on 14 Jul 1551 and died half an hour later.

Morbid stuff, sorry.
