A summary of the UK snow and ice risk warnings caused by Storm Caroline

Several sporting fixtures were postponed owing to snow and ice across large parts of the UK on Saturday.

In England, Bury against AFC Wimbledon in League One was postponed as a result of snow while Accrington Stanley v Swindon in League Two was called off because of a frozen pitch, while matches in Scotland were also affected.

But racing at Aintree, Wolverhampton, Sandown and Chepstow went ahead.

Weather warnings are in place, with heavy snow forecast into Sunday.

In the Scottish Championship, Inverness Caledonian Thistle v Falkirk was postponed on Friday because of snow, while Dumbarton v Livingston fell victim to a frozen pitch.

In rugby union, Edinburgh v London Irish in the European Challenge Cup has been moved to Murrayfield.

The match was supposed to be played at Myreside, but was switched to Scotland's national stadium as it has undersoil heating.

Is Manchester derby at risk?

BBC Sport's Simon Stone

Manchester United host Manchester City in the Premier League on Sunday at 16:30 GMT.

It is fair to assume no problems are expected with the Old Trafford pitch or the stadium itself.

However, if the surrounding areas become dangerous it would be a matter for the local council, the police and the club's Stadium Advisory Group to make a decision.

They would take into account road and rail networks for ease of getting to and from the game, plus accessibility of pavements in the areas surrounding the stadium and whether they pose a risk to safety.
