LONDON (Reuters) - Britain's foreign minister Liz Truss said on Wednesday that the situation in Northern Ireland was of grave concern, adding that the current trade arrangements weren't working and changes were needed.

       "The situation in Northern Ireland is of grave concern. The Belfast Good Friday Agreement was a huge step change for Northern Ireland in a positive direction. We're now seeing that undermined by the fact that the Northern Ireland protocol isn't working," she told Sky News.
