A heatwave continues to grip much of western Europe on Sunday, with high temperatures expected to persist well into next week.

In France, authorities have banned the consumption of alcohol at the annual Fête de la Musique (Music Day) festival in Paris, where temperatures are expected to reach 35° on Sunday. Parts of southern France and Spain are set to touch 40°C.

Météo-France says more than 30 French departments are under a red heat warning on Sunday, including Gironde and the Paris region.

Locals and tourists have nevertheless been making the most of the sun in the French capital, flocking to canals and parks over the weekend.

Emmanuel Grégoire, the mayor of Paris, announced swimming would be allowed in Canal Saint-Martin from Wednesday. He has also authorised Paris's parks and gardens to remain open 24/7 to help people looking for somewhere to cool off.
