If you're the constituent of one of the following MPs, then you really should write them a letter if you object to the Legislative and Regulatory Reform Bill. (The bill has a deceptively boring title - do read about it, get past the title) Heck, you should write a letter anyway - especially if your MP is labour, but people in these constituencies may well have a little more success. I've written to my MP, but these MPs are Labour Party candidates, and they rebelled against the government previously.
With thanks to Perfect.co.uk for the list.
Write To Them is a handy link which gives the addresses of your various representatives. Personally, I think snail-mail is a better bet than email.
