Staff at the Central Bank who are members of the trade union Unite are to vote on a motion of no confidence in senior management.

The union says the move follows the belated admission of a second secret bonus scheme, in addition to so-called "retention bonuses" which emerged last week.

Unite had been raising concerns about a bonus culture at the Central Bank since last May.

The union says it had specifically asked if there were any other bonus schemes in place after the retention bonuses emerged, and had been categorically assured that there weren't, but then yesterday, it was admitted that there was.
