DUP fined £1,000 for not declaring leader
The DUP has been fined £1,000 by the Electoral Commission for failing to notify it that Arlene Foster had become its new leader.
It said the DUP "failed to notify the Commission of a change in registered leader of the party by the required date".
The party has paid the fine.
Mrs Foster became DUP leader in December 2015, after the retirement of Peter Robinson.
A DUP spokeswoman said: "Due to an administrative oversight, the required notification was filed late.
"The Electoral Commission has indicated to us that they consider the matter closed."
The independent body which regulates political finance in the UK also fined Greenpeace and Friends of the Earth for breaking campaigning rules. At the 2015 General Election, non-party campaigners were required to register with the Electoral Commission if they spent more than £20,000 campaigning in England or £10,000 in Wales. Neither organisation registered, although the Commission's investigations identified over £100,000 in spending on their campaigns during the regulated period.
