This Part applies to any EU financial sanction imposed on the United Kingdom after the commencement of this Part, subject to subsection (2).
If a Minister of the Crown gives a certificate—
specifying a part or parts of an EU financial sanction, and
stating that this Part is not to apply to that part, or those parts, of the sanction,
this Part applies to that EU financial sanction as if it did not include that part or those parts.
A certificate under subsection (2)—
may make different provision about any of the following—
the lump sum (if any) paid by the United Kingdom;
any periodic payment due from the United Kingdom under the terms of the EU financial sanction before the certificate is given; and
any subsequent periodic payment that may fall due from the United Kingdom under those terms; and
must be given in such form and published in such manner as the Minister of the Crown giving it thinks fit.
Any provision of a certificate under subsection (2) which has the effect of excluding the whole or part of any periodic payment mentioned in subsection (3)(a)(iii) (including any such payment which has fallen due from the United Kingdom since the earlier certificate was given) may be varied by a further certificate under subsection (2).
