Bob Crow (may his testicles shrivel and fall off) has just announced another Tube strike, this one to last for four days. The BBC has the details here and more from Annie Mole here.
It's set for April 6th to 9th, but based on previous strikes I can see disruption to the network spilling over into the 10th as the strike won't end until 1830 on the 9th. Bastards. Aaaargh.
