Kelly McBride backs Labour in Brent East

Kelly McBride is backing Labour candidate Yasmin Quershi in Brent East , London – (the cosntitency with the largest Irish population in Britain). This is after assurances from both the candidate and the London Mayor, Ken Lingstone, that they will help her in the campaign for her murdered brother. Will this mean that this flagship Irish constutency will revert to Labour once again?
