Northern Ireland’s First Minister called for calm amid the row over post-Brexit trade disruption as the region’s police chief warned people to step back from the brink of violence.

Arlene Foster stressed that frustrations must be channelled through constitutional means after Police Service of Northern Ireland chief constable Simon Byrne warned of a “febrile” atmosphere.
