UK air passengers have been warned that they could face further disruption this week as another plume of volcanic ash threatens to move across the UK.

Airports in Portugal, France, Italy and Austria were forced to ground flights over the weekend, although the majority of airports across Europe have now reopened.

The Met Office warned the northerly winds which brought the volcano dust back to European airspace were likely to continue for some days.

"The ash is expected to come down the west side of the UK, but the impact on flights depends on what the volcano does," said a spokesman.

Passengers have been advised to check details of their flights before travelling to the airport.
