I think they’re saying they used to be one of the big boys. Now they’re just a regular boy.

When was the UK last in the top 2 countries globally by GDP? Certainly pre-WW2?

They're still in the same cluster of countries by GDP as the #3 country so falling from #4 to #6 doesn't look so drastic.

Weird, America usually goes "Regular, Big, Mega, King Size, Super Size, etc.", not the other way round!
