“It has been an extremely busy night for our firefighters and 999 control staff. Between 8pm on Monday evening and 7am on Christmas Eve, London Fire Brigade received 853 calls," a London Fire Brigade spokesperson said.
"This compares with 159 calls for the same period 24 hours earlier – that’s around five times busier than normal.
“Crews have been working incredibly hard throughout the night, mainly attending flooding incidents and fallen trees, as well as being called to structures such as windows, roof tiles and signs which have been left in a precarious position by the high winds."
