A Brazilian music festival headlined by the Pet Shop Boys has been cancelled.

The Roots were also among the acts on the bill for the Sonar Sao Paulo event, which was due to kick off in Sao Paulo, Brazil in May (13).

Organisers have now confirmed the music festival will not go ahead and blamed the cancellation on the "difficulties and instability in the Brazilian entertainment market".

A statement from the Pet Shop Boys reads, "We regret to report that Sonar Sao Paulo, Brazil, has been cancelled. Pet Shop Boys were due to perform at the festival on May 25th... Pet Shop Boys are hoping to perform in Brazil later this year and apologise to their fans for any disappointment."
