I truly believe you will be safe, in the centre of London and the west end where most of the tourist attractions are, has not been touched at all. it is beyond the centre in smaller boroughs that have been hit the worst. and I truly believe that they will have this situation under control before then, I have birthday plans at rainforest cafe in two weeks in town which I will not be changing, my grandparents went to the theatre tonight. like any city, it is about which area to go to, and in the heart of the commercial centre it is safe from these idiots
