20 Working Days received confirmation from the Cabinet Office that it holds information regarding the Prime Minister's orders for nuclear-armed submarine captains in their Letters of last resort.

20 Working Days is a publication created by journalist Tom Pashby, uncovering news stories using the Freedom of Information (FOI) Act. The FOI Act says organisations subject to the Act must respond “not later than the twentieth working day following the date of receipt” of a request, which is where this publication derives its name from. Subscribe for niche, but hopefully interesting articles about nuclear (power and defence), infrastructure, UK politics, environment, and some other stuff.
