This little stunt if true will do exactly the opposite. To be fair Brits are not really prone to protesting. However if Mr Trump (he really isn't presidential enough to be called president) has asked the PMk for these things.
I imagine even Mary Poppins would be getting out to throw a rotten cabbage or two in his general direction if he dared to show up.
You have to earn your affection in this country, and even if your popular person number one, the Brits are quite vicious when said persons popularity has dropped for what ever reason. Mostly because you turn out to be a fraud or a cheater.
Mr Trump ain't ever coming here again I think.
