Here's Piccadilly Circus in central London, normally one of the busiest junctions in London. Behind me is Piccadilly, to my left is Regent St up to Oxford St, the lone bus is coming from Shaftsbury Avenue (theatre land), and off to the right of heads over to Leicester Square and Trafalgar square. This was taken today, a dry Saturday at 2pm and in 20+ years of living here I've never seen it so quiet.
In a city of 9 million people it can be a challenge to achieve effective social distancing because of the Corona virus, and this is one of the last places and times you'd expect to be able to achieve it.
