I'm actually looking forward to whoever wins the election having to try to convince the public that spending £3 billion (an absurdly optimistic minimum, a few external sources have put it at closer to £6 Billion) to repair the HOC/Palace of Westminster is actually a good idea.
Of course if they really need the money, they could get Hugo Weaving to blow it up to the 1812 overture and charge us all £50 to watch.
If you watch the documentary series on the House of commons thenb you see what a state the place is in. Really needs quite a bit of work on it. The 6 billion is probably closer to the truth.
