Can the Queen pardon Tommy Robinson?
The Queen could grant ‘mercy’ which means that the conviction stands but the guy is released from prison. I don’t think the Queen really wants to get into the middle of this mess.
PM May likely has to agree to a confidence vote within ten days, which I doubt she will pass. So then, a nation-wide vote occurs again, and the Tories (her party) will have to discuss if she is the candidate (she won’t be), and if Boris Johnson is. At least a third of all Tories are anti-Boris.
Then you have the Tommy Robinson business. The UKIP folks might say there’s two issues here...BREXIT and a fake justice episode. I’ve seen a fair number of Labour folks and Tories who were just fed up with the treatment of Tommy, and would be willing to vote UKIP to solve that problem. Whether they could clear 40-to-50 percent of the vote is unknown.
Behind all of this....if there is a new election, I think BREXIT will conclude with NO treaty (remember, they have a deadline of late March 2019). If Boris got into the middle of this....there would be some major Trump-Boris dream team, and you’d find a lot of Americans pro-UK suddenly. With Trump around, you just can’t tell where this relationship would go.
