(quite a transformation from his earlier persona as a pretty ruthless political operator)
During those "early days" he was in his '60's! O/c there's nothing to say that you can't be both a canny operator
and a fundamentally decent person. Khabra was both IMO.
They tend to be dropped for by-elections, though the front-runner (the leader of the Labour group on Ealing LBC) is a women.
Did badly in Ealing as a whole, yes, but did well in Southall proper (over 50% in all five wards). The results in the West Ealing part of the seat were more typical of the borough as a whole o/c, but it's not as though those wards were voting Labour by 2005 anyway.
Parachuting in some token Asian Tory (for that is what it would look like, even if it would be unfair to think so) wouldn't really make much sense for the Tories electorally. The last thing they want is for their white vote to collapse and head LibDemward (for the LibDems will
presumably run their last counciller in the constituency; white and from the far east of the seat), what with the boundary changes coming next election (the best Tory, and best LibDem, parts of the seat are returing to Tory-target Acton...).
Acton returned a Tory from 1974 until 1997.
