Temperatures are expected to soar over the next few days – but how hot can the UK actually get? 

Although some outlets have predicted temperatures could reach a record-breaking 40C, East-Anglian based forecaster Weatherquest have said that it is more likely that figures will remain in the mid-thirties. 

As the county – and country – prepares for a scorching few days, we’re looking back at the UK’s top ten hottest days that have ever been recorded by the Met Office.
