With negotiations between the UK and the European Union (EU) - over a trade agreement - going down to the wire, the possibility of there being no deal is being talked about.

'It is hard to predict how full Brexit would play out, because this scale of multiple simultaneous renegotiations of global trade agreements is unprecedented – and no country has ever left the EU. It certainly can’t be assumed that Britain is bound to get quick and good deals because it is a large economy.'

Politicians have been bickering about Brexit for the past two years, but everything that has happened so far is just figuring out how we leave the EU - we still have to sort out what kind of relationship we have once we have actually left.
