The reformed group made the announcement at a press conference on board the HMS Belfast in London.
The band, who initially disbanded in 1989, will kick off the jaunt in Dublin on October 13.

In 1999, band members Tony Hadley, Steve Norman and John Keeble lost a court case with Gary Kemp for a £1 million share of songwriting royalties.
Tickets for the tour are available on general release from 9am on 28 March.
