Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign, Commonwealth and Development Affairs, with reference to the changes to the Green Book social time discounting rate to 3% announced by the Chancellor of the Exchequer, if she will take steps to revise the estimate of the net present value of the costs of the UK-Mauritius Treaty in respect of the future of the Chagos Archipelago.

The value of payments under the UK-Mauritius Treaty were set out by the UK government at the time of signature and have not changed. No payments are due under the terms of the UK-Mauritius agreement until the Treaty has been ratified. Full details of the proposed payments have already been published in the Explanatory Memorandum accompanying the Treaty.
