DUBLIN - Ryanair's British pilot union is to ballot members on possible strike action over working conditions in the coming weeks, the British Airline Pilots Association announced on Wednesday.

The results of the ballot are due on August 7 and strike action could take place two weeks later, the union told members in a memo.

The ballot is a setback for management who have in recent months said they had largely resolved an industrial relations dispute with pilots and cabin crew.
