I am today laying a departmental minute before Parliament describing a contingent liability that His Majesty's Government will take on relating to the United Kingdom’s participation in the AUKUS security partnership with the United States of America and Australia. His Majesty's Government will hold this liability following entry into force of the Geelong treaty between the UK and Australia, which I have recently signed along with the Australian Deputy Prime Minister.
As set out in the strategic defence review, AUKUS is an enhanced security partnership that will strengthen security in the Indo-pacific and Euro-Atlantic, along with growing the UK economy. The first major initiative of AUKUS is our historic decision to support Australia acquiring conventionally armed, nuclear-powered submarines. The treaty builds on the strong foundation of trilateral co-operation between Australia, the UK and the United States, advancing the shared objectives of the AUKUS partnership. It will enable the development of SSN-AUKUS and resilient trilateral supply chains.
As part of the co-ordinated approach to our respective SSN-AUKUS build programmes, Australia and the UK have decided to provide an appropriate indemnity to each other related to the supply of material, equipment, information and services transferred or to be transferred on a Government-to-Government basis in connection with SSN-AUKUS.
This contingent liability will not be incurred until entry into force of the treaty, which has also been laid before Parliament today. In accordance with usual practice for contingent liabilities, it will therefore not be incurred until at least 14 parliamentary sitting days have elapsed from the date on which the departmental minute is laid before Parliament.
