News of Buckingham's exit was first floated by ex-guitarist Billy Burnette on April 4, who wrote on Twitter that "Lindsey Buckingham is out! New line up to be announced soon and I'm not in it????? A little pissed off but I'll get over it." You can find his post below.
The band have enlisted Mike Campbell (Tom Petty and the Heartbreakers) and Neil Finn (Crowded House) for a forthcoming run of tour dates.
"Fleetwood Mac has always been a creative evolution," the group wrote in a statement. "We look forward to honouring that spirit on this upcoming tour.... The band wishes Lindsey all the best."
UPDATE (4/9, 4:40 p.m. EDT): Rolling Stone now reports that Fleetwood Mac actually fired Lindsey Buckingham after a disagreement over the band's upcoming tour.
Burnette replaced Buckingham upon his departure from Fleetwood Mac, remaining in the band from 1987 to 1995. The band's Christine McVie had mentioned the possibility of a 2018 tour in an interview last year.
"The 2018 tour is supposed to be a farewell tour," McVie told Uncut last March. "But you take farewell tours one at a time. Somehow we always come together, this unit. We can feel it ourselves."
Buckingham was asked to join Fleetwood Mac in 1974, following the departure of Bob Welch. He first appeared on the group's eponymous 1975 LP, remaining with the group until 1987. After contributing backing vocals on the band's 1995 LP Time, Buckingham rejoined the group full-time in 1997.
Buckingham and McVie released a duets album last year. Fleetwood Mac treated their 1975 self-titled LP to an expanded reissue earlier this year.
