North-eastern areas will be the worst hit by the wintry weather, and the Met Office has issued a yellow weather warning for ice during the early morning – including rush hour.

A separate yellow warning for snow and ice also covers a small pocket of south-east England until 10am.
Rain showers broken by intermittent patches of wintry sunshine are forecast for much of the rest of the UK.
