THE Unite union today launched a major campaign warning North Sea workers will be “betrayed” if Labour pulls the plug on new oil and gas licences without a plan, warning an estimated 30,000 jobs would be pushed “over a cliff edge.”

Labour leader Sir Keir Starmer has said his party would not grant licences in the North Sea but said it would continue with any licences already in operation.

The party’s biggest union backer has said the plans would be “dangerously premature and reckless.”
