British workers contracted for Belco’s North Power Station downed tools on Saturday after a delay in their paycheques.

Last night a spokesman for Belco’s parent company Ascendant Group said that the contractors’ payroll was delayed through their UK-based employment agency.

The industrial action involved an unknown number of staff at the project in Pembroke.

The spokesman added: “The issue was resolved within 24 hours and staff returned to work.”
