Christians should not be afraid of of speaking "freely" about their faith at work and in public places, Theresa May has said.

The Prime Minister said people should be able to celebrate Christmas as she endorsed a report which said that Christianity should be "celebrated, not denigrated".

The report says that many employers will have "little problem" with Christians discussing their faith at work "in the same way you might talk about sport, hobbies and family life".

Mrs May's intervention came after David Isaac, chairman of the Equality and Human Rights Commission, warned that over-anxious employers are failing to celebrate Christmas for fear of offending other staff.
