Firefighters are battling a huge blaze at the Littlewoods Pools building, one of Liverpool’s most famous landmarks.
Nine fire crews are at the scene of the blaze, which has extended upwards from the first floor of the building, Merseyside Fire Service said.
There are no reports of any injuries.
The five-storey Art Deco structure on Edge Lane was built in 1938 and was part of the Sir John Moores’ Littlewoods empire but has stood empty since 2003.
The fire service said it was first called at 19:52 BST and were on scene within four minutes, but found the roof well alight.
Crews using breathing apparatus have entered the building to tackle the blaze across an area measuring 200m by 100m from and two jets are being used to douse the flames from the outside.
The fire service said it has received close to 60 calls from members of the public regarding the fire.
The building had recently been sold with a plan to redevelop the site to become a major film and television studio hub, creating 350 jobs.
Twickenham Studios has signed a deal with developer Capital & Centric to create a £50m northern base at the site.
Mayor of Liverpool Joe Anderson tweeted: “Absolutely heartbreaking news that the iconic Littlewoods Building is ablaze, looks pretty bad at this stage, let’s hope and pray it’s salvageable.”
A police cordon is in place and the blaze is ongoing.
