Guys, saw briefly on yahoo.uk where strikes are scheduled starting 13 May, and on later dates. Let me apologize now for not being more specific, as it is late in Hannover, and have been busy at a show all day so don't know all the details. If coming to London in May, better check.
Specifically, as on BBC, the dates now released are: STRIKE DATES 16 to 17 May: 2101 BST - 1159 BST 18 to 19 May: 1200 BST - 1159 BST 20 May: 1200 BST - 2100 BST 13 to 14 June: 2101 BST - 1159 BST 15 to 16 June: 1200 BST - 1159 BST
17 June: 1200 BST - 2100 BST where BST means British Summer Time.
I hadn't noticed that this was posted to Transportation. I've seen discussion on the North about the strike.
It was announced this morning that the Tube strikes have been called OFF
