Look, if my life partner had just been elected PM and they wanted me to attend official events then I would want some nice clothes and no, with the world media watching me, I wouldn't be looking at M&S or Zara, sorry.
But hell's teeth, I'd pay for them myself or, if I were offered a gift, the first thing I'd do would be to check the rules, especially if my partner were issuing dire warnings about painful budget decisions.
It's so strange, it's the kind of behaviour I normally associate with a government that's been in power for too long and got lazy and careless, not from one that's only just taken office.
