OK then instead of:
"The UK has been colonised by immigrants, really, hasn't it? I mean, the population of the UK was 58 million in 2020, now it's 70 million. That's 12 million people." Jim Radcliffe
You are fine with:
The UK has been colonised by immigrants, really, hasn't it? I mean, the population of the UK was 58 million in 1995, now it's 70 million. That's 12 million people."
So your main complaint then is not what he said but that he got his dates wrong.
