The Manchester four-piece claimed the prize for their raw number one album “A Brief Inquiry into Online Relationships” ahead of Florence + The Machine and indie singer George Ezra.
The band also claimed the best British group award — speaking out against misogyny in their acceptance speech — before performing “Sincerity Is Scary” for the thousands packed into the London’s O2 Arena at the 39th annual ceremony, which recognised Britain’s top talent of 2018.
Australian A-lister Hugh Jackman kicked off proceedings in a blaze of Hollywood razzamatazz, performing “the Greatest Show” from hit musical “The Greatest Showman” accompanied by scores of gravity-defying dancers.
George Ezra was the night’s early winner, taking the Best Male Solo Artist award, beating off competition from garage pioneer Craig David, veteran avant-garde techno producer Aphex Twin and soul singer Sam Smith.
He followed up by performing upbeat summer chart-topper “Shotgun”, shortly before 21-year-old soul diva Jorga Smith was named best female solo artist.
US superstar Ariana Grande and hip-hop giants Drake and The Carters — comprised of power couple Jay-Z and Beyonce — scooped the international awards, with the latter sending a video thank you message in front of a regal painting of Meghan, the Duchess of Sussex.

The Brit Awards have recognised the cream of British pop music since they were first held in 1977, and have often been peppered with scandal and farce.
The 1989 Brits are best remembered for the shambolic presenting skills of model Samantha Fox and Fleetwood Mac’s Mick Fleetwood and a comical series of mishaps.
Pulp frontman Jarvis Cocker stormed the stage in protest while Michael Jackson performed surrounded by children in 1996.
In 1998, Chumbawamba vocalist Danbert Nobacon dumped a bucket of iced water over then deputy prime minister John Prescott.
And Madonna suffered whiplash injuries at the 2015 edition when she fell off the stage wearing a giant cape and surrounded by dancers wearing bondage-style costumes and horns on their heads.
The awards have also been criticised for failing to be bold in their choice of performers in recent years.
