UK’s largest oil and gas producer warns against tougher windfall tax

Harbour Energy says higher levy and extended timeline will deter investment despite profits bonanza

The UK's largest oil and gas producer has warned Rishi Sunak against toughening up the windfall tax on North Sea operators as the prime minister finalises plans for a 40bn raid on the industry.

Harbour Energy urged the government to carefully consider" any mooted change to the energy profits levy, which was introduced earlier this year.
