Last week, for the first time in my life, I wished I lived in Streatham, the south London suburb of bowling alleys, chicken takeaways, skating rinks and social insecurity. It has one jewel, however: Chuka Umunna, the sitting Labour MP. Mr Umunna does not follow his party leader; he is not, therefore a card-carrying, grievance-mongering Leftie. He has described himself as “One Nation Labour” and “Blue Labour”. He is keen on social justice and free markets. Some might suggest he is a bit of a libertarian, but I have no wish to be rude to the man. On the contrary, if I lived in Streatham (rather than in achingly hip Balham) I’d give serious consideration to voting Labour – something I have never done before.
