Northern Ireland voters evenly split over post-Brexit protocol, poll finds Rebecca Black Belfast city centre - PA Wire 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. A new opinion poll conducted by LucidTalk for a team of researchers at Queen's University Belfast, has found that a majority of people in Northern Ireland have concerns about the current impact of the Protocol.
