Barclays boss: UK will remain financial lungs of Europe

Jes Staley, chief executive of Barclays, says the UK will continue to be the "financial lungs" of Europe even after it leaves the EU.

Speaking to BBC business editor Simon Jack at the World Economic Forum in Davos, he adds that not so long ago "no-one quite wanted a banker in their back yard, and all of a sudden we're being invited over to the barbecue".
