Some stupid ideas here to rebuild the House of Parliament somewhere other than London.
The Houses of Parliament does not exist in isolation.
Don't people realise that the whole area around there (Whitehall) is full of Government buildings (10 Downing St for example but also many major Government departments containing thousands of civil servants).
Moving JUST the Parliament building elsewhere would cause all sorts of administrative headaches and would be totally unworkable.
p.s. Having said that, when I see the inside of the House of Commons on a busy day like Budget day, and we have MPs sitting on the stairs and standing around the edge you do realise the building awfully badly designed for the number of MPs we have (I know there are plans to reduce the number of MPs).
We are one of the major democracies of the world, and we have a building that cant even hold all the MPs when a full debate is on. How embarrassing for our country.
