When will Parliament close for refurbishment, how long will Westminster be shut and where will the Commons and Lords go?
The refurbishment programme will be the first time since the Second World War MPs and peers will move out of the Palace of Westminster
MPs and peers will move out of the Palace of Westminster for the first time since the Second World war while a multi-billion refurb takes place.
The six-year renovation programme will see everyone who works in the building relocated to a temporary new home.
What's wrong with the Palace of Westminster?
A study in 2016 found the Palace has deadly fire risks, collapsing roofs, crumbling walls and leaking pipes - as well as large quantities of deadly asbestos.
The Joint Committee on the Palace of Westminster said: "The Palace of Westminster, a masterpiece of Victorian and medieval architecture and engineering, faces an impending crisis which we cannot responsibly ignore.
"It's impossible to say when this will happen, but there is a substantial and growing risk of either a single, catastrophic event, such as a major fire, or a succession of incremental failures in essential systems which would lead to Parliament no longer being able to occupy the Palace."
Why are MPs moving out of the Palace of Westminster?
The Joint Committee has rejected the possibility of MPs staying in the building while repairs are carried out.
It said while there is no risk of the building collapsing, despite "extensive erosion and water damage", there are major issues with the services and utilities installed.
The Committee suggested a "full decant" option - with both the House of Commons and House of Lords moving out - is the only plausible way forward.
They added: "Unless an intensive programme of major remedial work is undertaken soon, it is likely that the building will become uninhabitable."
MPs voted in favour of moving out of the building during the refurb and rejected Theresa May's preferred option to delay the decision.
When will MPs and peers move out and how much will the refurb cost?
They will move to a temporary home for a six-year period to pave the way for a full repair of the crumbling building, which will cost taxpayers up to £6billion.
But they won’t move out before the next election in 2022 and a move is not expected to take place until 2025 at the earliest.
A new delivery body will be established to provide up to date costings of the work and a “realistic” timetable for the repairs.
They will also create new legislation to guarantee MPs and peers return to the Palace after the renovation to address fears they will go back to the historic building.
Where will the MPs and Lords go?
The Commons is planned to move to Richmond House, on nearby Whitehall, which is currently home to the Department of Health.
The Lords would relocate to the Queen Elizabeth II Conference Centre, just off Parliament Square in Westminster.

Alternative options included a partial move, in which the Commons and the Lords moved one after the other.
Another mooted plan had been to put MPs in a new temporary structure on the River Thames.
Regional politicians had also argued parliament should move to other cities such as Birmingham and Manchester to take the opportunity to spread engagement with politics to other parts of the country.
