I think Starmer needs to get himself in line with other industries. IMO he should not have accepted anything at all. Additionally, measuring himself by what Bojo accepted is also unacceptable - it's not ok just because Bojo got a load of stuff (also wrong IMO).
Over the past 20 years, things have changed a lot. My dh (who is just a pleb, nobody famous or anything) is allowed to accept nothing other than a meal, and only if work is being discussed at the meal. In previous years, people offered football tickets - he can no longer accept these. He also has to be careful with stuff received at Christmas. Regardless of who it's addressed to, everything is shared and nobody receives anything worth more than about £10-£20.
Many schools have limits on the gifts teachers can receive - they must declare or even decline them. Often it's about £50. So if a teacher can't even get £50 on top of their very average salary, it's appalling for Starmer to get £100,000 worth of anything. It should all be returned or donated to charity - immediately. And rules are needed - MPs can accept nothing, end of.
