LONDON - British Prime Minister Boris Johnson on Saturday praised Northern Ireland's political parties for reaching a 'fair and balanced deal' after three years of deadlock and said the restoration of the region's executive would improve lives. 'This is a momentous day,' Johnson said in a statement after Northern Ireland's elected Assembly returned to work and swore in a First Minister and Deputy First Minister. 'As we begin a new decade, we can now look forward to a brighter future for all in Northern Ireland with an Executive that can transform public services and improve people's lives,' he said.
