Why do they protest so much? Isn't it a perfectly legitimate tactic for a party leader to seek to put his opposite number on ths spot over an issue - particularly when they have brought the problem on themselves by being less than open about it in the past?
But whatever the low politics of the situation, it's the right move by Gordon. Cannabis is evil shit and I have witnessed at first hand the kind of psychosis it can induce in regular users, in my case in a former landlord. An old newspaper colleague of mine, Huw Lewis, had an experience that was, sadly, even closer to home.
And in case anyone's wondering....yes, I did, once or twice, and all it ever gave me was a bloody headache.
