The Democratic Unionist Party is to end its 16-year boycott of the British-Irish Inter-Parliamentary Body.
The party will send a delegation to the organisation’s meeting in Killarney, Co Kerry, later this month.
The BIIPB comprises parliamentarians from all parts of Britain and Ireland and was set up after the Anglo Irish Agreement. However, unionists have consistently shunned the body.
The DUP decision to send a delegation, headed by Deputy Leader Peter Robinson, will be seen as evidence of a further thaw in the party's attitude in advance of next month’s meeting of the reconvened Stormont Assembly.
