Presuming the allegations are true, all I can think is how basic the whole affair is. TV has made me come to expect something more complicated and devious.
That being said, earlier this year there was a story here in the UK about King Charles once receiving 1 million in cash (in a shopping bag!) from the Gulf as 'charity donation'... so perhaps EU politicians should setup more charities.
Edit: in fairness, the cash donation to Charles' charity was correctly booked and reported in the charity's accounts and so nothing much happened when the story broke. But bags of cash do tend to raise eyebrows and the conclusion was that it'd be best not to accept them in the future...
You can raise your eyebrows all you wish, I'll stick with the bag of cash, thank you.
