General election: Jeremy Corbyn says Treasury document proves there will be N Ireland checks news.sky.com

Boris Johnson has said it is "complete nonsense" to suggest his Brexit deal will lead to customs checks.
Jeremy Corbyn says he has obtained a confidential Treasury report which "drives a coach and horses" through Boris Johnson's claim there will be no Irish Sea border after Brexit.

The Labour leader said the document, marked "official, sensitive", provides "cold, hard evidence" the prime minister has been "misleading" people about his withdrawal deal.
