Secondary picketing is illegal in this country. So why is the RMT turning out at the London Fire Brigade Union protest? Is Bob calling in the comrades?

Note the massive RMT banner…

It is interesting to note that 22 MPs are sponsored by the RMT including London MPs Dianne Abbott, Stephen Pound , John McDonnell and Jeremy Corbyn. Will there be a wall of silence from these normally outspoken MPs? What role is Bob Crowe playing in these strikes?
