Plan B needed to resolve northern impasse, say 'realistic' Sinn Féin

Leo Varadkar must come up with a plan B to resolve the political impasse in the north, Sinn Féin has warned.

The party's president Mary-Lou McDonald said her party will go into negotiations next week "with every ounce of energy that we can" but she remains "realistic" that talks may not break the deadlock to restore the Assembly.
