Elections in London: mayor for Tower Hamlets?

I intend writing more about the coming polls in Tower Hamlets, but I haven't finished reinforcing my tin hat. The deep and often bitter complexities of local Labour and Respect rivalries - see David Boothroyd's summary of the borough scene - are reflected in the two parliamentary campaigns - see here and here - and in the parallel ones for and against the Council following Hackney, Newham and Lewisham in introducing a directly-elected mayor. At a debate on that issue last month, George Galloway, Ken Livingstone and Keith Vaz spoke in favour of the change. Read the speeches of Galloway and Livingstone to get a whiff of the wider battleground. The "no" argument is made here.
