The Cabinet Office has confirmed to 20 Working Days that it holds information regarding what options the Prime Minister has in terms of the orders they can give to nuclear-armed submarine captains in their ‘Letters of last resort’, but said it is withholding the information.

It is widely understood that one of the first tasks a Prime Minister has on walking through the door to Number 10 Downing Street is writing the letters to the captains of Trident submarines – the UK’s continuous-at-sea-deterrent.

The letters are written so that, if communications are not possible between the submarine and the wider military and political command and control structure, the submarine captains are able to find out what they should do by reading the pre-written letters which are believed to be sealed until they are needed.

The existence of the letters was confirmed by the MOD in an internal review of a FOI request in 2015. The results of the internal review were addressed to a Mr D Black.

In 2016, just before Theresa May took over the role from David Cameron, the Guardian reported: “The options are said to include the orders “Put yourself under the command of the US, if it is still there”; “Go to Australia”; “Retaliate”; or “Use your own judgment”.”

On 4 July 2026, using the FOI Act, 20 Working Days asked the MOD to share “any documents which show whether the options include the orders ‘Put yourself under the command of the US, if it is still there’; ‘Go to Australia’; ‘Retaliate’; or ‘Use your own judgment’,” as per the reporting in the Guardian.

In response, on 16 July, the MOD said: “As the letters are administered by the Cabinet Office, you may wish to approach them regarding […] what options the letters might contain.”

On the same day, 20 Working Days put that question to the Cabinet Office.

On 17 August, the Cabinet Office responded and said: “We are writing to advise you that following a search of our paper and electronic records, we have established that the information you requested is held by the Cabinet Office.

“Information you have requested is exempt under section 24(1) of the Freedom of Information Act. Section 24 exempts information from disclosure if its exemption is required for the purpose of safeguarding national security.”

It added that “Section 24 is a qualified exemption and we have considered whether the balance of the public interest favours releasing or withholding this information”, and confirmed “we have determined that the balance of the public interest favours withholding this Information”.

The Cabinet Office was approached for comment.
