Nuclear Safeguards Bill

The best example I can give is the ratification of the agreement with the US—and this will also explain the difference between signing and ratification. Now that it has been signed, it needs to be approved in accordance with the relevant constitutional requirements of the UK and the US, just as will be the case with the other bilateral agreements, but we have built into our timetable sufficient time to allow for the necessary processes in both the UK Parliament—it will come before Parliament this year—and the US Congress, which has a slightly different arrangement involving several days of congressional business. I am very confident, however, that the process will be completed. In both cases, it is unprecedented for this to be anything other than a formality. Both countries will then exchange notes to bring the agreement into force when required, which we fully expect to be at the end of the implementation period, but we have built plenty of time into the process.
