And would you care to give me the ethnic origin and nationalities of all those extra people in Bude, Keith?

How should I know? Why is that relevant Steve?

"extra millions"
Hyperbole.

In 2015 the population increased by 513,000 people (0.8%), and that is typical for recent years.

About half of the people coming to the UK in 2015 were from the European Union. Recent data indicates that there are approximately 3 million EU citizens living and working in the UK. This equates to 5% of the UK population. The other half came from non-EU countries.
