Matilda leads Olivier nods with 10 nominations

Matilda the Musical, based on Roald Dahl's popular children's book, leads the race at this year's Olivier theatre awards with 10 nominations out of a possible 10.

It started as a subsidised production outside London, but has now been transformed into a West End hit.

It's part of a powerful new trend, as the BBC's arts correspondent David Sillito reports.
