Tony Hadley has vowed never to speak out on why he quit Spandau Ballet.

The singer was frontman of the group, which scored hits in the 80s with classic tracks like True and Gold, but walked away from the five-piece in 2017.

He’s credited tensions between himself and guitarist Gary Kemp for the departure, but told Daily Mail he “never will” say more than that.

The group formed at school, with Gary and brother Martin – the group’s bassist – along with Tony, multi-instrumentalist Steve Norman and drummer John Keeble.

They first broke up in 1990, reunited in 2009, split up in 2017 and are on an indefinite hiatus.

Explaining his long-running squabbles with Gary, Tony shared: “We were always the ones who argued.

“He’s got a very strong personality and so have I. And it could produce an atmosphere that was not very pleasant.

“I was amazed to hear him say recently that we grate on each other but we have such a laugh sometimes,” he added. “Really? If it was such a laugh, I would never have left.”

When asked if Gary and brother Martin – the group’s bassist – would be ashamed of the reasons why he left, Tony insisted: “Yes… If it ever got out, yes they would.”

He also claimed the backstory would damage their reputations, adding: “[Gary’s] quite a complex character.

“A lot of things have happened… And that is all I am going to say.”

While Tony recently released solo single Obvious, the sibling duo poked fun at their past as ’80s icons and disputes with Tony in their BBC mockumentary The Kemps: All True.

In the show, Gary’s character painted a picture of Tony with devil horns, and the singer insisted it was the last straw for him, telling The Sun he was not asked to appear and would have refused to take part if he had been.

“I wasn’t approached and would not have anything to do with it,” he shared.

“I’m done. They want me back for good but it ain’t going to happen. I’d rather be happy on my own than be in that band again.”

He also accused the group members of selling out for cash, suggesting their deals have tarnished the band’s musical legacy.
