UK Parties Debate Nuclear Policy as Lib Dems Push Independent Deterrent

The Conservative, Labour, and Liberal Democrat parties have all pledged in their manifestos to maintain the UK's current nuclear weapons policy for the 2024 election, according to party documents. The Conservative Party manifesto highlights steadfast support for Trident, increased Ministry of Defence spending, and aims to raise MOD spending to 2.5% of GDP by 2030. In contrast, the Green Party opposes the UK's nuclear deterrent and would push to cancel Trident, remove foreign nuclear weapons from UK soil, and sign the UN Treaty on the Prohibition of Nuclear Weapons. The Liberal Democrats support maintaining a credible minimum nuclear deterrent with continuous at-sea deployment but advocate for a 'No First Use' policy and renewed disarmament efforts, as stated in their manifesto.

The Liberal Democrats' stance includes internal contradictions: leader Ed Davey argues the UK should develop an independent nuclear deterrent due to unreliable US support under Trump, citing dependence on the US for Trident missile maintenance, while the party's policy supports maintaining the current Trident system, which is US-dependent. In 2016, seven Liberal Democrat MPs voted against Trident renewal, with none voting for it, according to research from six sources. It remains unclear whether the Liberal Democrats' support for a 'No First Use' policy conflicts with maintaining continuous at-sea deployment, or the feasibility and cost of developing an independent UK nuclear deterrent as suggested by Ed Davey.

Conservative leader Kemi Badenoch suggested Liberal Democrats have 'bad views on national security' and might not want to keep the nuclear deterrent, a claim that contrasts with the Liberal Democrat 2024 manifesto's support for maintaining the deterrent. This criticism adds to the political friction over defense policy ahead of the election.

Technically, the UK's nuclear deterrent, known as Trident, consists of Trident II D5 missiles carried by Vanguard-class submarines, with continuous at-sea deployment, according to research from six sources. US nuclear weapons were withdrawn from the UK in 2008, but nuclear-capable B-52 bombers are routinely based at RAF Lakenheath, the same sources report. Whether US nuclear weapons could return to the UK remains an open question.

Defense spending provides context for these debates: the MOD's 2023-2033 Equipment Plan includes spending exceeding the budget, assuming the MOD budget rises to 2.5% of GDP, with current UK military spending at around 2.3% of GDP, research from six sources indicates. NATO states agreed to increase military spending to 2% of GDP, first as a guideline in 2006 and reaffirmed as a pledge in 2014, according to the same research. How the MOD's Equipment Plan spending exceeding budget will be addressed if the MOD budget does not rise to 2.5% of GDP is not specified.

The Green Party's comprehensive anti-nuclear and arms control agenda extends beyond Trident: the party would also seek to end arms sales to Israel, according to the Green Party. The specific impact a Green Party ban on arms sales to Israel would have on UK involvement in programmes like the F-35 is unknown.

Geopolitically, Vladimir Putin has made veiled nuclear threats, and Russia suspended participation in the New START treaty, research from six sources reports. This backdrop underscores the high stakes of UK nuclear policy discussions.

Liberal Democrat media strategy and political attacks include MP Lisa Smart criticizing Reform UK as having 'swivel-eyed Trump supporters' and ties to Russian connections. Lisa Smart stated she is 'always delighted to accept the invitation' to appear on GB News, according to Lisa Smart, despite her party leader calling for GB News to be censored. This highlights the party's nuanced approach to engaging with media outlets while attacking political rivals.
