We are all deeply affected by the situation in Afghanistan and the human tragedy that we are seeing. All MPs and their staff understand that constituents are extremely anxious about their friends and relatives in Afghanistan and want to do all they can to help them.
Every MP is trying to help a lot of desperate people and only your own MP is able to help you, so if you do want to ask for assistance please email only your own MP.
If you copy in all MPs, you are actually hindering them in their efforts to help people as quickly as possible. It may feel that you are more likely to get attention if you contact lots of MPs, but this is not the case.
If you are actively seeking assistance for your relatives, please read this page: https://w4mp.org/w4mp/w4mp-guides/in-the-constituency/casework-guides/issue-by-issue/afghanistan/
