Sinn Féin president Gerry Adams will launch his discussion on Irish unity at Westminster later today.
Mr Adams will meet MPs, Irish community representatives, trade unions and academics.

It will lay out plans for a major conference in London in mid-February, seeking to involve broad sections of society, a Sinn Féin spokesman confirmed.
