so why the fuss,
Why isn't this sinking in? Anyone who has worked in the public sector, particularly in a position of any influence, will know that public servants are not allowed to accept gifts over a certain value. This is rigorously observed. Had it been a local council employee who had been given £58,000 to pay for refurbishing their home there would be universal condemnation and the employee would be sacked.
The purpose of this rule, which has been in existence for decades, is to ensure that public officials cannot be influenced to favour, say, a dubious planning application. It applies to all public servants, from highest to lowest They cannot be 'bought'. They are supposedly incorruptible.
Johnson's decor was initially paid for by roundabout ways, and certainly not by him. It was paid for by a 'donation' to the tory party specifically earmarked to pay for the refurb. The donor has since, surprise surprise, landed some nice lucrative government contracts. This is text book corruption! The 'gift' was not declared. This is against the rules, too.
Bozo only paid up when the story started to emerge. One might infer that he'd actually had no intention of paying for the refurb but got caught breaking the rules, so dug in his pocket (or, for all we know, into someone else's pocket).
The Electoral Commission is going to investigate him for breaking electoral law in respect of donations. They would not be doing that had they received an answer to their initial enquiry which proved beyond doubt that he had not broken electoral law.
This issue is not just one of bad taste, it is one of potential corruption.
