Under section 12 of the Political Parties, Elections and Referendums Act 2000 (c. 41) the Electoral  Commission is required to keep under review the terms of the Scheme and to make  recommendations to the Secretary of State for any variations to the Scheme which they consider  appropriate. The changes made by this Order give effect to those recommendations. The list of  parties eligible for grants is amended to include the Social Democratic and Labour Party following  the general election on 12th December 2019. The formula for determining a party’s weighted vote  share, which enables the Electoral Commission to calculate the amount to be allocated to each  party in accordance with paragraph 5 of the Scheme, is amended so that it no longer takes into  account European Parliamentary elections.  An impact assessment has not been produced for this instrument as no impact on the private or  voluntary sectors is foreseen.  © Crown copyright 2020  Printed and published in the UK by The Stationery Office Limited under the authority and superintendence of Jeff James,  Controller of Her Majesty’s Stationery Office and Queen’s Printer of Acts of Parliament.  3 “Determination of Democratic Unionist and Social Democratic and Labour shares  EXPLANATORY NOTE  (a) add the notional shares calculated in accordance with paragraph 7 for the  Democratic Unionist Party and the Social Democratic and Labour Party; and  (b) divide the resultant amount by two.”.
