Opposition Day Debates (20th Allotted Day)

On the 20th allotted Opposition Day, 24 March 2026, the Conservative opposition raised Oil and Gas and Defence as the topics for debate.

1 Oil and gas: 

“That this House calls on the Government to remove the Energy Profits Levy, end the ban on new oil and gas licences and approve the Rosebank and Jackdaw fields to increase secure domestic energy supply; recognises that the North Sea provides half of the UK’s gas supply, supports 200,000 skilled jobs across the UK and generates billions of pounds in tax revenue; further recognises that three quarters of the UK’s energy needs are met by oil and gas, that the UK will continue to use oil and gas for decades, and that the North Sea is the UK’s most secure and lowest-carbon source of oil and gas; notes that without action to make the sector more investable, the UK risks importing 82% of its gas by 2035 at higher cost and with higher emissions; and further notes that independent analysis by Stifel shows that the Energy Profits Levy will cost the Treasury more than it raises and that reforming it would generate an additional £25 billion in tax revenues within 10 years.”

The Motion was rejected: Ayes 108, Noes 297 and the Prime Minister’s motion was resolved: 

“That this House welcomes the Government’s approach to the future of the North Sea, which maintains existing oil and gas fields for their lifetime, as well as introducing Transitional Energy Certificates while accelerating the transition to clean energy; notes that new licences to explore new fields would take many years to come online and would make no difference to energy bills; recognises that oil and gas prices are set on international markets; and further welcomes the measures announced by the Government to go further and faster on national energy security by reducing reliance on volatile fossil fuel markets and expanding secure, home grown clean energy.”

2 Defence

“That this House regrets that the Defence Investment Plan has still not been published despite the Government promising Parliament that the plan would be published in Autumn 2025; notes that the Government’s delay has frozen procurement and has stopped the UK from learning lessons from its long-standing support for Ukraine and left the UK vulnerable as the world becomes more dangerous; believes that the Northern Ireland Troubles Bill and the Northern Ireland Troubles (Legacy and Reconciliation) Act 2023 (Remedial) Order 2025 should not be proceeded with because they are a threat to morale, and that the Diego Garcia Treaty should not be ratified to ensure that the UK continues to have sovereignty over its military base; calls on the Government to publish the Defence Investment Plan as soon as possible; and further calls on the Government to increase spending on the UK’s armed forces, specifically delivering 20,000 more troops over the next Parliament, paid for by restoring the two-child benefit cap, and redirecting net zero funding to defence, to ensure that the UK spends three per cent of GDP on defence by the end of this Parliament.”

A closure motion was moved, and the House agreed to put the motion to a vote, which was rejected: Ayes 98, Noes 306.
