Sally Bercow has told more than 45,000 followers on Twitter that the government's ban on the legal-high mexxy has made her tempted to try it before it is too late.
The wife of Commons Speaker John Bercow wrote on the social networking site: "Am I the only one now slightly tempted to try mexxy before it becomes illegal? I won't, obvs."
Later, she added: "Oh, the mexxy ban is only 'temporary'. What's that all about? (Am now obsessed with the stuff, despite never having heard of it 1/2 hr ago)"
The drug was made illegal temporarily by the Home Office on Wednesday. Used as a supposedly-safe alternative to Class C drug Ketamine, it is a dissociative anesthetic which has been blamed for the death of a 17-year-old boy.
