As someone who lives outside the UK, and travels a fair bit I have to say that the view that Starmer is impressive on the world stage is definitely not held by most of those outside the UK. It's a bit of Labour spin as far as I can see. He is mainly laughed at... Articles such as 'Why can't Starmer afford to buy his own clothes', 'why does the British PM always misjudge those around him', 'why does he always look like an outsider at international events', 'why does he always claim deals that are never quite as they seem'. He's seen as untrustworthy basically
And, as with Mandelson, there's a degree of incredulity that he can be bought so cheaply...
