Around 150 firefighters have been tackling a blaze at an office building in London's historic law district.

The London Fire Brigade was called to Chancery Lane in Holborn at 10.40pm after receiving reports of a fire at the six-storey building.

A large section of the roof and parts of the third, fourth and fifth floors were alight, a fire brigade spokesman said.
