Actually I was in London for a hospital appointment three weeks ago and a friend came to support me so we decided to stay for a couple of nights.
For three days we wandered around the centre of London, two old vulnerable ladies, peering at Google maps on our phones, going to the theatre, eating our lunch on a bench in the park, walking along the Embankment late at night to see the lit cityscape.
Not once did we encounter anything unpleasant or feel insecure or threatened.
In fact there was a point in the park with us on the bench amongst other elderly people, children racing around, business people enjoying their lunch hour in the sun and groups of teenagers just hanging about together when I wanted to take a video to say “This is London”.
The press and others on here might disagree with me but that was my experience.
