LONDON, July 12 (Xinhua) -- The British government on Thursday published a long-awaited white paper on Brexit, seeking to create a free trade area with European Union (EU).

The document, entitled "The Future Relationship between the United Kingdom and the European Union", is expected to set out a comprehensive and ambitious vision for the UK's future relationship with the EU, delivering the right balance between rights and obligations, according to the government.

It will see Britain leave the Single Market, and the Customs Union.?
