This is the election of a lifetime – and there's only one way to win it. Stopping Boris Johnson's extreme Tories, and stopping Brexit, will come down to how many people decide to vote tactically this time.
That's why we are launching a mass, grassroots tactical voting campaign, combining social media with leafleting and digital ads to spread the message as far as possible.
Stopping the Tories means explaining what tactical voting is, and how to do it, to millions of people who may have never heard of the idea before.
We know from our 2017 general election experience, and our work so far in this election, that every £20 donated lets us tell an extra 1,000 people about tactical voting.
Over 900,000 people have looked up their constituency's tactical voting recommendation here on tactical.vote since the election was called. The site has over 150,000 likes and shares on Facebook and is currently the top-ranking site on Google for most UK tactical voting searches.
Our simple method and open data approach means we are the most transparent tactical voting site, and we made the most accurate tactical voting recommendations in 2017. Your donation will help us reach even more people as the election reaches its conclusion.
In some seats, a few thousand votes could make all the difference. Please give whatever you can to make sure as many people as possible hear the message about tactical voting.
Note: If you donate more than £500 than we will check your details to see that it is a permissible donation, under Electoral Commission rules, and may be in touch with you to confirm this. Anonymous donations are not accepted. Multiple donations from the same person will counted as one donation for recording and reporting purposes. If you donate more than £7,500 in total then your name will be published on the Electoral Commission website.
