ALMOST 100 celebs joined forces yesterday to pile pressure on David Cameron to step up the government’s commitment to reunite stranded refugees with their families in Britain.

Actors Mark Rylance and Jude Law, musician Paloma Faith and left-wing film directors Ken Loach and Mike Leigh are among the star-studded cast to sign a hard-hitting open letter to the Prime Minister.

Their plea calls on Britain to “step up and do more” to help “vulnerable refugees.”
