A quarter of a million pounds is unlike anything the DUP has spent in the past. Just a month before the EU referendum, the party won 38 seats in the Northern Ireland Assembly elections and retained its position as the largest party there.To do this, they spent less than £90,000.The 2015 general election – where the DUP won eight seats and became the third-equal biggest group in Westminster – cost the party only £58,000. In fact, the total combined spend of all Northern Irish political parties for the 2015 general election was just £221,143.The DUP’s most recent accounts show that its total expenditure for the whole of 2015 was £511,766, and its net assets at the end of the year were around £195,000.A bill of more than £250,000 only months later would therefore have left them bankrupt – unless they got significant extra income from somewhere.
“They’re from an organisation in England that wants to see the union kept, and to make sure we can have a United Kingdom because it was a national issue.” DUP leader Arlene Foster
