The Hester comments have highlighted the risk of taking donations. I would be more concerned with what did Hester expect in return.

Dale Vince donated large sums to Labour to further his business in the expectation of a favourable green policy in the event of a Labour government.

As has been pointed out, Vince said of Hamas, " one man's terrorsit is another man's freedom fighter "

Ashworth accepted a lot of money from a suspect Chinese source.

Glass houses etc.

All this just highlights the worsening hypocrisy and self interest
prevailing in politics

Responsibility Deficit Disorder is a medical condition. Symptoms include inability to be corrected when wrong, false sense of superiority, desire to share personal info no else cares about, general hubris. It's a medical issue rather than pure arrogance.

There is disquiet among some Conservatives about the willingness to accept money from Hester, whose software firm has won lucrative NHS and prison contracts, after the Guardian revealed he told a 2019 meeting that seeing Abbott on TV made “you just want to hate all black women”.

The bigger the donation the bigger the pay-off.
