Scotland, Northern Ireland and Wales have all recorded their warmest day of the year so far, with the former two countries reaching temperatures they have not hit in years, as the third heatwave of the summer peaked.

Highs of 30.8C have been recorded in the Scottish Highlands, as the Met Office says Northern Ireland has seen its warmest day since 2022.

Fire chiefs have urged people to stay safe as they warned of the increased risks of wildfires and drowning during the heatwave.
