Alan Keen, the Labour MP for Feltham and Heston, has died aged 73.  We will write more about the consequent by-election in due course, but it is right now simply to send commiserations to his family.  His wife, Ann Keen, was MP for Brentford and Isleworth from 19997-2010.

Noon update: Total Politics has some of the tribues being paid to Mr Keen.
