A report by the National Cyber Security Centre reveals that the Chancellor’s November Budget was accessed nearly 25,000 times ahead of its official publication due to a leak from the Office for Budget Responsibility (OBR). An initial review suggested it has been downloaded about 43 times. The probe also found that Chancellor Rachel Reeves’s Spring Statement last March was accessed 16 times before her speech, not once as previously thought. The leak forced OBR chairman Richard Hughes to resign. The Treasury now says it will tighten security around forecasts and keep dates of OBR evaluations secret.
