An igloo built and slept in by a group of Bristol university students has been praised as a "great job" by an expert.

Ted Oakes, from the BBC's Natural History Unit, has lived in an igloo with Inuit people and said the students had done well considering they did not know what they were doing.

The students used the snowy conditions to raise money for homeless charity Crisis.
