I agree with GG13 and the others who say we shouldn't be trying to associate this with any political party. The issue for me is that an illegal activity was taking place in the Houses of Commons. now whether you think it happens everywhere, or drink is worse, or anything along those lines, it doesn't change the fact that its illegal.
The Gove video - I won't share it as that is perpetuating it and he might just have had an off day. But search online for Gove accused of being ‘drunk or on drugs’ and you'll see its not made up. If you can get over your distaste for Googling, that is.
