Air and rail passengers are being hit by more travel disruption even as temperatures cool after the hottest July day on record.

It comes as the Met Office received a new provisional recording of 38.7C in Cambridge on Thursday, which – if confirmed – would be a new temperature record for the UK.

The railway network still faces heavy delays and cancellations after soaring temperatures caused overhead cables to sag. Great Northern, Thameslink and East Midland Trains are among the train companies affected with passengers advised to avoid travelling unless the journey is essential.

Meanwhile, the Met Office has issued a severe weather alert over the weekend warning of potential flooding in north, northeast, northwest and southeast England.
