LONDON (Reuters) - British 1970s reggae band UB40 is backing Jeremy Corbyn in his campaign to be re-elected as leader of the opposition Labour party, calling the left-wing leader "incorruptible" and welcoming his commitment to the arts.

UB40, whose hits include "Red Red Wine" and "Can't Help Falling in Love", is the biggest musical name so far to back Corbyn, who is expected to fend off a challenge to his leadership this month.

"Jeremy has re-ignited an interest in politics for people who no longer felt included, and engaged and inspired a new generation of young voters who, for the first time, believe that they have an incorruptible politician who truly represents them," UB40 said on its Facebook page.

"Westminster needs big change, and Jeremy is the man to do it."

Corbyn, a veteran left-wing campaigner, has brought many new members into the party but has deepened divisions between its left and right wings following its defeat in last year's parliamentary election under previous leader Ed Milliband.

Corbyn has pledged to reverse cuts in arts spending made by governments over the past few years.
