London Zoo's animals get a taste of winter

But Nicky the pygmy hippo - originally from tropical regions in Africa - took a brief look outside before deciding to stay indoors.

The British Meterological Office has issued a warning of dangerous conditions after heavy snowfall across much of the country.
