Northern Ireland voters evenly split over Brexit Protocol – poll Anti-NI Protocol sign (Liam McBurney/PA) People in Northern Ireland are “highly exercised” and “evenly split” over the Brexit Protocol, an opinion poll has indicated. The Protocol, which introduces fresh checks on goods arriving into the region from Great Britain following the UK’s departure from the EU, sharply divides opinions at Stormont, with unionists strongly opposed to it. Loyalists have been holding demonstrations against the Protocol across Northern Ireland in recent months while a number of legal challenges have been lodged against it.
