You're a bit too young and naive Matt!
I never expect these Labour people to act in a principled way. "Labour leaders break strike" is a headline some of us have been used to seeing over the last few decades. Last time I remember even a modicum of solidarity was Shirley Williams turning up to the Grunwick picket line, 1977 I think - almost a revolutionary act by comparison with today's Labour (and LibDem) leadership. Labour scabbed on the strikes in the "Winter of Discontent" in 1978/9. Kinnock's "grotesque" speech at the Labour Party conference became somewhat ironic when the Labour council in his own backyard in Glamorgan handed out redundancy notices in the same way. And of course he did nothing to support the miners. These people don't know what "solidarity" means.
I'm glad the Greens supported the strike by the way. Well Done!!
