Boris Johnson rubbishes Labour claims about Brexit deal customs checks

The transcript discusses the uncertainty around Jeremy Corbyn's position on the EU, different views on the election, and the Brexit deal. It highlights the benefits of the deal, particularly for Northern Ireland, which remains part of the UK's customs territory with unfettered access to Great Britain. The only checks will be for goods moving from Northern Ireland to Ireland, preventing a hard border. The transcript concludes with the option for people to opt out of the deal in four years if they disagree with any part of it.
