Where did the money come from?

Most candidates have a stab at listing donor details but these details are pretty sparse - most of the funds appear to have come direct from the political parties, at either a national or regional level. When you look for the detail you see a handful of individual donors (eg retiring South East Cornwall MP Colin Breed gave Karen Gillard £250,) but their contributions are dwarfed by centrally-administered funds.

Some campaigning, of course, was nationally directed and there was no requirement to declare it on individual candidates' returns: those big David Cameron posters, for example, don't appear on any of the local expenses documentation because they were part of the national campaign.
