This is about so much more than wallpaper. A pattern of lying, betrayal and callousness is ruining lives

Yes, it’s a real scandal. Despite the apparent absurdity of a Westminster village obsessing over soft furnishings and the precise class connotations of the John Lewis brand, there is a hard offence underneath all those cushions and throws. By refusing to tell us who first paid for the refurbishment of his Downing Street flat, Boris Johnson is denying us – his boss – the right to know who he owes and what hold they might have on him.

Offence is the right word because, even before the Electoral Commission determines whether the law on political funding was broken, Johnson’s failure to come clean may well be, by itself, a breach of the ministerial code. That bars not only actual conflicts of interest between ministers’ “public duties and their private interests” but even the perception of such conflicts. In refusing to tell us who first paid that bill for overpriced wallpaper, or to give full details of who paid for his December 2019 holiday in Mustique, Johnson has offended the public trust.
