In today's column, Polly Toynbee says:
Party fundraising did for Chancellor Kohl, the man who united East and West Germany at great political and financial risk
Polly also says of the Tories' proposed cap on donations of £50,000 that:
The unions this week gave indignant evidence that the cap would cut their annual contribution to Labour from £8m to £800,000.
Actually, these figures refer only to affiliation fees and not the total contribution, as this article in the Guardian makes clear:
The proposals would mean the unions, Labour's chief source of funding, would only be able to provide £800,000 annually instead of the present £8m annually in affiliation fees alone.
Indeed, a bit of digging on the part Electoral Commission's website dedicated to funding (here) shows that in 2005, unions gave the Labour Party £11.8m in cash alone, of which £2.8m was in donations below the proposed cap of £50,000 (though some of these may be multiple donations from the same union).
