UB40 lead singer Ali Campbell is to quit the group after almost 30 years, the band has confirmed.
Ali Campbell is to concentrate on his solo career
Campbell, who sang on hits such as Rat In My Kitchen, and Red, Red Wine, intends to concentrate on his solo work, the band said in a statement.
The Birmingham reggae band's last gigs together will be next month in Australia, New Zealand and Uganda.
A spokesman for the band said they would continue to record and perform with the existing seven members.
A decision on who will replace Campbell has not been made.
The band's spokesman said: "Ali Campbell has taken the decision to focus on his solo career and in doing so, could not give his full commitment to UB40.
"The other band members of UB40 are naturally disappointed and saddened after being together as a band unit and as good friends and a family unit for almost 30 years."
He added "UB40 will continue to record and perform with the existing seven members.
"UB40 has never been about any one individual, but more a collective of band members, who have all contributed to create the unique sound that UB40 have become renowned for over the last three decades."
The band's next album 24/7, which features Campbell, will be released as planned.
Formed in 1978, UB40 have sold in excess of 70 million records, including three UK number one singles in Red, Red Wine, I Got You Babe, and Can't Help Falling In Love.
They also had two UK number one albums in Labour of Love and Promises and Lies.
