Fianna Fáil leader Micheál Martin has accused Sinn Féin and the DUP of creating a dangerous vacuum in Northern Ireland.

He said both parties' ministers in the Northern Executive show no interest in bridging differences.

Speaking at his party's annual 1916 commemoration at Arbour Hill in Dublin, Mr Martin accused the Government of not seriously engaging with Northern Ireland.

He also said the Government was taking the most partisan approach to commemorations in 30 years.
