Flights to and from Scotland have been cancelled and police have urged motorists across Tayside to drive cautiously after temperatures plummeted to -11C overnight.

British Airways said Heathrow Airport is “continuing to experience severe adverse weather conditions” and reduced its flight schedule for Monday.Â
