Horse racing cancellations: Four upcoming race meetings have been entirely called off due to extreme heat forecasts across the United Kingdom.

Wednesday's scheduled fixtures at Kempton, Salisbury, Worcester and Ffos Las will no longer take place.

Warnings from the Met Office: The cancellations come after the Met Office upgraded its weather warning to a rare red alert for central and southern England as well as Wales.

This warning indicates a potential risk to life, with temperatures expected to reach a scorching 38C from 9am on Wednesday until 9pm on Thursday.

Welfare measures for horses: The British Horseracing Authority strictly follows a hot weather policy that dictates fixtures must be abandoned if they fall within a red warning zone.
