Two RMT branches, Bakerloo Line and Finsbury Park, have recently passed this motion in defence of free movement, and calling for solidarity with refugees and migrants.
The motion also calls for RMT-backed MPs to vote against any Brexit deal that restricts immigration and attacks workers' rights.

The motion is slated for debate at the union's AGM in June.
