Chancellor George Osborne has confirmed that he will cut North Sea oil and gas taxes.
He pledged to reduce the supplementary charge from 32% to 30%, expand the ring-fenced expenditure supplement from six to 10 years, and introduce a new cluster area allowance.
The UK Government insisted that the changes would trigger billions of pounds of investment in the North Sea and create thousands of new jobs.
The cut in the supplementary charge represents a partial climb-down by the chancellor, who infamously almost wiped out investment at a stroke when he hiked it from 20% to 32% without consultation in 2011.
