Want to help Labour campaign? Here are top 50 marginals where you’re needed

A number of people have contacted the SKWAWKBOX to ask where they can best invest their time and effort to help Labour win the General Election.

Below is a list of the 50 tightest marginal seats, along with the 2015 winning margin, who won and the total electorate. In each of these, help to attack – or defend – the seat is vital.

Pick one or more within reasonable reach and dive in. Your country needs you.

The top 108 potential targets all have a majority of fewer than 4,000, so if none here are convenient or you have time and want to do more, see the full list of seats here.

  1. In order to win a majority of just 4, the Labour Party need to keep hold of the 229 seats they have already and win an extra 100 seats!

    Labour can’t form a government on their own. Use the below website to discover the most potentially successful anti-Conservative/UKIP candidate in your constituency and support him/her.


  2. Excellent to see this list, its how members could put their efforts in. Make the vote wider not deeper 👍
    Hope to see you out within these areas.

  3. Please add Stroud in Gloucestershire. We had an excellent Labour MP from 1997-2010 and do have a chance of winning the seat back. Open Britain said they’ll back our Tory MP as he’s a Remainer (but always votes as he’s told) so we need help! Please.

  4. Wonder if you know of Jeremy Corbyn’s campaign trail dates? I joined the Labour Party last year because of him and the direction he has taken the Party, steering it back to its roots. I’m delighted that my 22yr old daughter has become very enthused about politics, again because of Jeremy, and she and a friend are really keen to go and see/hear him speak. I have tried tweeting and I have emailed the Labour Party, but as yet no luck, thought I would try you;-) My daughter and friend are based in the North West; Bolton/Blackburn.
    Thanks for a great news service!

      1. I did wonder if that was the case, thanks for replying anyway:-)
