Then
£500 – Value of Ford Anglia accepted as a gift by trustees of Chequers in 1955, causing members of Anthony Eden’s government to fret that ‘gifts of this kind present difficulties’ over ethics.
Now
£150,000 – Gift Boris & Carrie Johnson were perfectly happy to accept from donor to build a tree-house for their son at Chequers.
That link led to a post of mine, some 6 years ago, that showed the goodwill and affection that many ABers have for each others.
It's worth a read if you have time.
My employer’s anti-bribery policy requires me to declare any gifts I receive above the value of £25 (€30); my manager would then give approval for the gift (or not), and may elevate it within the company for a decision.
I very much doubt my employer would permit me to receive a gift of £150,000. But it is interesting that a large percentage of ABers see nothing wrong in receiving such a gift (clearly their morals are closely aligned with those of Boris).
