The UK could experience the hottest day of the year so far on Friday.
The Met Office has warned people not to be “caught out” by the potentially record-breaking temperatures.
The mercury is set to rise to 37C in London and the south east on Friday and could surpass the 37.8C recorded at Heathrow on 31 July – the hottest day of the year so far and the UK’s third warmest ever.
It is the second day of a heatwave which is expected to last until at least Sunday.
