This started as one of those stories that was very very simple. A rich but slightly controversial businessman wants to give shedloads of cash to Labour and uses friends and employees to do so without being named personally. Labour's General Secretary - the most important paid official in the party - knew of this very dodgy and illegal practice. He resigned. Simple? Well, no...
Now it is claimed that these friends-of-Ambrahams have also donated to the funds of cabinet ministers including Deputy Leader of the Party, Harriet Harman, who is also married to the Labour Patry Treasurer. Now it also seems the the Environment Secretary, Hilary Benn, may also have benefitted. Yet nobody within either camp bothered to check who these donors were because, if they did, they would discover that such people were unlikely to be able to donate such four figure sums.
And to make it worse, poor Justice Secretary Jack Straw (who is becoming Gordon Brown's lightening-rod-in-Chief) went on Channel 4 to say that no cabinet minister knew of this.
Oh dear...
