Brexitwatch: let's get pro-Remain parties to work together

If we're going to stop Brexit, it's really important that pro-Remain parties do very well in the local elections on May 2, and the European elections on May 23 (assuming they happen), so I've written to the LibDems, the Independent Group and the Greens to ask them what they're doing to work together.

Here's what I sent to the Independent Group:

It is very important that pro-Remain candidates do very well in the local elections and the European elections (assuming they take place).  So I would like to know what you are doing to co-operate with other pro-EU parties such as the LibDems, the Greens, the SNP etc. I am writing to the other parties asking the same question.
