March 29, 2019, marks the deadline for the UK to leave the EU, and there are two ways in which it can happen: the so called "Hard" and "Soft" Brexits.
A Hard Brexit arrangement would likely see the UK leave not only the EU but also the EU’s Single Market (of which non-EU countries like Norway and Iceland are also members) and the EU Customs Union (of which non-EU countries are also members). The UK would instead aim to secure free trade deals with the EU, ideally covering both goods and services.
A Soft Brexit, on the other hand, would likely see the UK leave the EU but maintain access to the single market. In return, it would have to make payments into EU budgets and accept the "four freedoms" of movement of goods, services, capital and people.
If the UK ends up leaving not only the EU but also the single market, and stops observing the "four freedoms", this question will consider that a Hard Brexit and be resolved as "Yes".
