Parliament repair bill 'could top £3bn'
- Moving MPs and peers out completely for five years, closing the entire Palace of Westminster. This would be expected to encounter significant political opposition
- A "partial decant" - the House of Lords and the House of Commons would move out in turn, so one half of the palace could be restored at a time, which would take considerably longer
- Politicians refuse to move and construction takes place around them. That could take decades and cost even more
