Number 2, The EU And Number 1, The USA

European Union, the second largest economy in the world

European Union (2015) 16.335 trillion GDP (current US$)

The USA, the largest economy in the world

United States of America (2015) 17.95 trillion Gross Domestic Product in USD

The first world economy is the USA. USA gets all it's information about Europe fed to it from the British (Empire) media, who want to separate from Europe. So who's going to be the liar?
Trying to find the GDP of (Greater) Britain is a pain. They use different measurements.

GDP of United Kingdom

United Kingdom/Gross domestic product 2.849 trillion USD (2015)

Since Brexit Greater Britain has made
zero
nought

trade deals, giving it a total of zero points.

Since Brexit, the EU has established Free Trade deal with Canada

Canada/Gross domestic product 1.551 trillion USD (2015)

Also likely to secure trade deal with Japan

Japan/Gross domestic product 4.123 trillion USD (2015)

Total points 5 trillion

The USA wants to push down EU as number 2(poo), and the UK wants to ignore the EU(poo) as number 2, which is why USA hosts recite what the British media tells them to. So, there's no reason to listen to anything American hosts say about Europe, it's all taken from Britain, and they can't even claim it's by the Queen's implicit orders since the Queen's speech 2017.
