Just above minimum wage would seem very insulting to me even if it was a new post Hilton wage structure.
Wasn’t the ‘just above minimum wage’ claim from his wife on social media too? Seem to recall that but may have got it wrong. No idea what the actual truth is on this aspect.
I’d suggest that when Mrs Butterfield said “just above minimum wage” it was a deliberate downplay to mislead supporters into thinking he’d been offered £12 an hour.
