Tourism sites including Acropolis to close during hottest parts of day as temperatures set to remain over 40C

Greece is set to endure its hottest July weekend in 50 years, a top meteorologist has warned, as the country wilts under a prolonged heatwave set to last well into next week.

Government ministries have advised people to work from home where possible and not to venture out unnecessarily. The exceptional temperatures also mean key tourism sites will be closed during the hottest part of the day.
