Northern Ireland unionists have expressed alarm after the shadow Northern Ireland secretary, Peter Kyle, said he would be prepared to call a referendum on Irish unity if certain conditions were met.

Kyle would set out the criteria for calling a border poll if Labour were in power, he told the BBC’s Sunday Politics show at his party’s conference.
