Multiple sources say the deployment of HMS Duncan is under consideration; Yvette Cooper says flight will take off from Muscat this week

Ellie Chowns, the Green party’s foreign affairs spokesperson, has said she has tabled an “armed conflict (requirements) bill’” which would require any UK military intervention to have a lawful basis, viable objective and approval from MPs.

In a letter addressed to the prime minister, which she shared to X, Chowns, who is the Green’s MP for North Herefordshire, wrote:

In recent days we have seen a deeply concerning escalation in conflict in the Middle East following a series of illegal and dangerously irresponsible airstrikes on Iran by the United States and Israel.

You have now confirmed that UK bases will be used by the US for their operations in the area. This is a significant concession to President Donald Trump and one which risks drawing the UK into a dangerous conflict.
