[...] By contrast Irish exports to GB were up almost 8% year-on-year to €4.1bn (£3.4bn); that may reflect the fact that the UK has still not imposed full import controls on EU goods. Official figures showing trade between Northern Ireland and Great Britain are only published on an annual basis, so it may be 2022 before there is solid data on how Brexit and the Irish Sea border has had an impact on those relationships.
