“Households in England urged not to go outside between 11am and 3pm on Sunday”

“Residents in parts of England might be well advised to stay indoors on Sunday between 11am and 3pm as soaring temperatures are likely to blast parts of the country. According to the latest BBC weather forecast, Sunday will see highs of 26C in London and Manchester.”
