Of course not, and his excuse will be "the Tories will use that to paint us as anti-children", when in reality, the surveillance state is older and more engrained than any party.
The Tories have ruined the country, but I wish people stopped seeing them as pure evil against the pure good that is Labour, which is far from the case. They're all rotten in their own way, and it's not them pulling the pervasive surveillance strings. I wouldn't know who is for certain, but it's a combination of being in the Five Eyes, our friendship with the USA, the very favourable media, and the cultural fact that British people have been OK with total surveillance for decades.
