Brexit: What is the Irish backstop?

The video discusses the UK-EU agreement on the Irish border, focusing on the backstop, an insurance policy to keep Britain in the EU customs union if no other agreement is reached. The UK and EU have differing views on the backstop's content. The EU suggests Northern Ireland remain in the EU customs union, while the UK opposes this, fearing it would harm the Union. Failure to agree on the backstop could lead to a no-deal Brexit, resulting in a hard border with strict checks between Northern Ireland and the Republic of Ireland.

How does Britain view the idea of a separate status for Northern Ireland?

What are the potential consequences of a no-deal Brexit as mentioned in the text?
