Brexit

The impact on free trade was the most asked about subject. Below, BBC Economics Correspondent Andrew Walker looks at two of the most popular questions you asked:

  • Why does [Mrs May] think we'll get a free trade agreement when [we're] opting out of the free movement of goods, services and people?
  • What's the difference between the "freest possible movement of trade and goods" and the single market as we know it?

The only thing on the list above that the Prime Minister has said she wants to opt out of is the free movement of people - or rather the free movement of people to work and settle in the UK.

She is very keen on the free movement of goods and services. She said in the speech that she wants: "the freest possible trade in goods and services between Britain and the EU's member states."

She does not want to opt out of that.

The freest possible means what we have today. For example: no tariffs on goods travelling in either direction, mutual recognition of each other's technical standards, the freedom to offer services across borders and more.

In short, it means the provisions of the single market that apply to goods and services. It would be theoretically possible to go further still, especially in services. The European Commission says there are still barriers and it wants to tackle them.

But for now, the single market as it is represents the freest we can get.
