According to the BBC, Sinn Féin in Northern Ireland alone had net income of over £1m from donations and grants whilst the DUP – which leads the Northern Ireland Assembly – made a loss of £27k.
This might explain why the DUP were so keen to join the Conswervatives who are in a far better financial position than Liebour or the Illiberal Dipshits.
It seems that the only way a party can hope to get serious money (other than selling peerages, of course) is to sit on an extreme fringe. Sinn Féin advocated the use of terrorism to further their agenda and were rewarded with vast amounts of cash, a lot of which was raised in that bastion of democracy and anti-terrorist fervour, the US. The BNP advocate forced repatriation of immigrants and curtailing freedom of the press and are rewarded with bucket loads of cash from all over the place, again including the US.
