Britain has recorded its hottest day of the year so far, as the country basks in the heatwave brought by an “enormous” bubble of warm air from the Sahara.

A temperature of 34C was recorded at Heathrow on Saturday afternoon – soaring past the 33C highs experienced in the Caribbean island of Jamaica today.

Temperatures were set to climb further this afternoon, with the south east expected to see the most intense conditions and highs of 35C forecast for London.

The Saharan winds that have been spreading scorching temperatures across the continent don't look set to give Europe a break today.

Temperatures could reach new record-highs again in France, Belgium and Switzerland. In Spain, officials are warning that more ‘significant’ wildfires could break out as the mercury reaches 45C.
