My comments below not specific to the BBC.
It occurs to me that in this country the establishment has institutionalised corruption. Why run the risk of a nosy reporter spotting you taking a brown envelope.
So the establishment realised there was another way to get their readies. We have a myriad of Quangos, and other no show jobs, which pay out a nice little earner, and don't forget the expenses, those hotel suites don't come cheap.
Then of course there is the gongs, all in all they look after each other, which is why a socialist party like Labour does nothing about it. Even they realise how useful it is to lob a cushy part time job or a knighthood to one of their supporters.
Only in this country could we come up with a system that institutionalises corruption.
