OK, I'm being picky, but the Liberal Democrats claim that the Tories have no MPs in Birmingham.
While the Tories in Sutton Coldfield have considered seceding from the union, at last count they remained inside the City of Birmingham, as they send a cohort of councillors in to run the city.
You can see why they chose to ignore it, though. The Liberal Democrat candidate there slid back on the 2001 results while the Labour candidate actually increased his vote since then. (Nice one, Rob).
