Re: But I thought we "took back control" @Richard
This original law was drafted before the referendum, when the government thought that they would remain in Europe, so they should have expected to have this type of battle on their hands.
As such, it's got sod all to do with the result of the referendum, and much more to do with the fact that Home Secretaries (and I include Ms. May in this category) think that they have valid reason to ride roughshod over the privacy of Her Majesties subjects. This is true what ever political colour they have been. Remember Wacky Jackie?
