Dear Commissioner,

We, the undersigned, request that the Metropolitan Police Service assess whether any offences under domestic law may have been committed by Secretary of State for Health and Social Care Wes Streeting MP and his cabinet colleagues in relation to the United Kingdom’s continued material and political support for the State of Israel during the ongoing conflict in Gaza.

This request is made in light of:

1. Messages between Wes Streeting MP and Lord Peter Mandelson in which Streeting acknowledges that Israel is committing war crimes and committing targeted and calculated acts of violence against non-combatants, including women and children .

• For example, Mr Streeting wrote in 2025: "Israel is committing war crimes before our eyes. Their government talks the language of ethnic cleansing and I have met with our own medics out there who describe the most chilling and distressing scenes of calculated brutality against women and children.”
• In this same release of messages Mr Streeting, a serving Cabinet Minister throughout this period, accused Israel of "rogue state behaviour" implying  criminality with no regards to international or humanitarian law.
• When Lord Mandelson suggested that the wrong action could lead to "further deadlocked death spiral on an even greater scale than now" Mr Streeting responded that "Israel is doing it anyway", acknowledging the scale and ongoing escalation of Israel's crimes.

These communications are understood to have been released by Mr Streeting himself, and have been widely reported on by the British press and broadcast media.

2. The UK Government’s ongoing provision of military, intelligence, logistical, and diplomatic support to Israel during the relevant period. 

• Arms exports from the UK to Israel during the period in which Mr Streeting assesses that Israel were committing war crimes reportedly include components for F-35s (rear fuselage, targeting systems), Watchkeeper WK450 UAVs, and components for armoured vehicles. 
• Intelligence support includes alleged spy flights over Gaza, with surveillance imagery and intelligence shared with Israeli military intelligence, as reported by multiple, credible, independent investigative journalism organisations in the United Kingdom. 
• Logistical support reportedly includes the flight of large cargo transport planes from RAF Akrotiri to Israel during the same period. 
• There are also credible allegations that the UK Government - at the bequest of the Israeli government, military, intelligence services and/or corporate interests - took action to suppress domestic protest movements against Israel's war crimes and the complicity in these war crimes of Israeli arms manufacturers operating the UK.

Under UK constitutional norms, Cabinet Ministers are bound by collective responsibility for government decisions. This means that Mr Streeting shares equal responsibility with the rest of the cabinet for any material support provided to Israel during the commission of war crimes by that state.

3. The UK’s legal obligations under:

• The Arms Trade Treaty, which prohibits authorisation of arms transfers where there is a clear risk they could be used to commit serious violations of international humanitarian law.
• The International Criminal Court framework as incorporated into domestic law via the International Criminal Court Act 2001.
• The UK Consolidated Criteria governing arms exports.
• Provisional measures and proceedings concerning alleged violations of the Genocide Convention before the International Court of Justice.

If a Cabinet Minister acknowledged in private communications that war crimes were being committed, and the Government nonetheless continued material support, serious legal questions arise as to whether any offences relating to aiding, abetting, counselling, or procuring international crimes may have been engaged under UK law.

We submit that the combination of:

• Acknowledgement of ongoing war crimes,
• Continued material and diplomatic support, and
• The UK’s binding international and domestic legal obligations

creates a prima facie case warranting formal assessment by the appropriate authorities.

We therefore respectfully request that the Metropolitan Police:

• Assess whether the available evidence meets the threshold for investigation under the International Criminal Court Act 2001 or any other relevant statute;
• Clarify the jurisdictional basis for any such assessment; and
• Confirm what steps, if any, will be taken.

Given the gravity of the alleged underlying crimes - including alleged acts of violence against civilians and crimes potentially up to and including genocide - transparency and adherence to the rule of law are essential.

Yours faithfully,

The undersigned.
