The United Kingdom’s Brexit Minister says the Northern Ireland Protocol is doing more harm than good - and is creating severe challenges in the region. Northern Ireland is the sole area where the UK and the European Union physically meet - along its 500km (310 miles) border with Ireland. Keeping that border open is a crucial part of the 1998 Good Friday Agreement that ended the long-running conflict in Northern Ireland that killed more than 3,000 people. To avoid any physical border checkpoints, the ‘Protocol’ created a customs divide in the Irish Sea instead - which is inside the UK. The UK’s David Frost is adamant that it must change, and he revealed a proposal for a new, amended deal on Tuesday. However, reaction from the EU - set to unveil its own proposal on Wednesday - has been lukewarm at best. Al Jazeera’s Andrew Simmons travelled to see what effect the dispute is having in Belfast, Northern Ireland.
