Leaked Brexit document did not reflect final version of deal - UK source

A leaked document used by the Labour party to attack the governing Conservatives' Brexit deal was written by a junior civil servant and was an initial appraisal of the deal and not formally approved, a British government source said on Friday.

British opposition Labour leader Jeremy Corbyn said on Friday he had a confidential government report which showed there would be customs checks between Northern Ireland and mainland Britain under a Brexit deal negotiated by Prime Minister Boris Johnson.
