A statement from the band - who called Brookes "one of the finest drummers of his generation" - read: "Jon was a brilliant drummer, an inspiration, a founding member of The Charlatans, part of our family and a friend to everyone in and around the band.
"Losing someone who was always so full of life is a tragedy that will be shared by so many. Our thoughts are with Debbie and all of Jon’s family."
The band's singer, Tim Burgess, tweeted: "Jon Brookes, my friend, our drummer and inspiration to so many, passed away this morning. We are torn apart. Love & thoughts to Jon's family."
