volcanic ash cloud has cleared from the UK and now disrupts European airspace, but forecasters predict its return to Britain later this week.

The National Air Traffic Service has confirmed that UK airspace is now clear of ash from the Icelandic eruption and should remain clear for some time to come.
But Transport Secretary Philip Hammond said the ash plume, although now less intense, is expected to return as winds shift.
"The volcano has paused so at the moment… but it is predicted to come back later in the week," he told Sky News.
Pressure is mounting on the Civil Aviation Authority (CAA) to reduce impact on travel plans as families across Britain prepare to jet off on half-term school holidays.
"The Met Office and the CAA will be doing a lot of modelling work to minimise disruptions," Mr Hammond said.

The Met Office has released a cloud spread prediction for 6pm tonight
Meanwhile BA has conducted an approved test flight into the ash cloud's red zone, with boss Willie Walsh announcing that no damage occurred to the plane.
His company has submitted a safety case to the CAA asking for permission to continue flying its planes.
Around 500 flights have so far been cancelled in the UK this week, leaving many stranded at airports in Scotland and northern England.
But now those travelling to and from Europe face further chaos, as the cloud begins to blow over northern countries.
