Also on the programme: decision time for Andy Burnham, who has less than 24 hours to decide whether to plot a return to Parliament.And Minneapolis grinds to a halt as opponents of immigration enforcement raids hold a general strike in the city.

We hear from a correspondent who’s spent time on the front line in the Donbas. Also on the programme: Westminster is flung into speculation as a Manchester seat is to become vacant, potentially giving Andy Burnham a route back into parliament.
