John xxxxxx, we've just seen a massive increase in Tory spending online.

They've taken their billionaire's budget and they want to drown social media in advertising, inundating YouTube, Facebook, Twitter and Instagram.

They want everyone to see Tory lies and spin as soon as they log on.

We want to compete. We want to show people our powerful message of change. It's our last chance.

Can you chip in now?

We don't have million-pound cheques, but we have a plan. We only need to reach the right people in the final few days of the campaign – people who need a reminder to get out to the polls, especially in areas where the results will be neck and neck.

We already have a ground-game that the Tories could never dream of competing with. With online advertising, we can make all the difference on polling day – and win.

Don't wait until it's too late. Chip in now to change the course of history.

Thank you,

John McDonnell
Shadow Chancellor of the Exchequer

We can't sugar coat this. There's two days to save the futures of millions of people.

It's in your hands. Please chip in whatever you can.
