We have received a report that there is currently a fire at Tesco. Apparently there is a lot of smoke and a fire engine has arrived. Everyone seems to be safe.
Update: at 6pm, I spoke to a fireman, still at Tesco, who said the “fire was in the store room and we still don’t know the cause.”
Update: The Richmond & Twickenham Times have an article on the fire with a few more details.
