King, Queen and Prince William will join Aberfan survivors to mark 60 years since a coal tip killed 116 children

On Wednesday the King and Prince William will each lay a wreath where Pantglas Junior School stood, followed by a prayer and a silence. William is also to unveil a memorial tree at Ynysowen Community Primary School. The 1966 collapse killed 144 people on the final day of term before the half-term break. On Monday Prime Minister Andy Burnham said Aberfan 'was not treated properly by the authorities'.

Jeff Edwards, then eight, was the last child pulled out alive, spotted by his blond hair.

David Davies was laid among the dead until someone saw his foot move.

Dave Evans, now 86, is thought to have been the person who first telephoned the fire service that morning.
