Political - Speak to your MP at Parliament

How to 'Green-Card' your MP to speak to them in person
If you happen to be around the Houses of Parliament you can green-card your MP.
For times, try calling the Commons Enquiry line on 020 7219 4272.
What you need to do:

Go through the Cromwell Green entrance to parliament and pass through security (allow for this to take up to 20 minutes).
Queue up at the information desk in the central lobby and you will need to collect and fill in a “green card.”
Hand the green card to the information desk. The information desk will be able to let you know quite quickly if your MP is not at the House of Commons.
If your MP is unavailable the fact that you have handed in a green card will mean that your MP will know you have requested a meeting and your MP will have to write to you in due course letting you know their views.
If the information desk does manage to contact your MP be prepared to wait for a while.
