French-based aerospace company Airbus has been in a Brexit "holding pattern" before committing itself to its future in the United Kingdom.

Japanese electronics company Panasonic and banks Nomura and Daiwa have moved their European headquarters from the UK, which currently absorbs 40 percent of Japanese investment in the EU, and a report published by Ernst and Young revealed that financial institutions have shifted 800 billion pounds ($1.03 trillion) of assets out of the country as contingency planning for a no-deal Brexit.

According to the City of London Corporation, Britain's financial sector employs 2.2 million people, and contributes 12.5 percent of the country's GDP, generating 72 billion pounds in tax revenue－so to the outsider, evacuation in high finance coming on top of a slump on the high street might look like another example of the Brexit contagion May is struggling to contain.

But according to Christian May, editor of London daily business newspaper City AM, things are not quite that black and white.
