Where any overseas increase taken into account in the calculation of a supplement is revised with retrospective effect, that supplement shall be revised with similar effect and any overpayment of supplement thereby identified shall be repaid to the Secretary of State.

Any sum repayable under paragraph (1), and any sum paid in respect of supplement which is recoverable by the Secretary of State apart from that provision, may (without prejudice to any other means of recovery) be recovered by deduction from supplement paid to the pensioner in respect of any pension.
