Cars are submerged and some polling stations are closing as flooding affects London and the South East.
London Fire Brigade said it received about 550 emergency calls and had attended more than 400 incidents, including flooded premises and properties hit by lightning. London Fire Brigade said its crews were being “mobilised to incidents as quickly as possible” but urged people to only call 999 in an emergency – “where there is a risk to life or property”.
Two polling stations in Kingston and another in Barking closed after rain fell in some areas.
