So the general feeling is that it is Kate, but with a discreet female bodyguard.
Considering she had been recieving death threats it's a brave thing to do. I could not imagine M blending in so well that there was a "is it really her?" debate.
No it’s the truth not a general feeling. And there is no way ( quite rightly) that she would have gone had there been a credible death threat. She wouldn’t have been allowed and even more importantly she’s the mother of 3 young children and would never have risked leaving them motherless.
