"Sinn Féin negotiators stand ready," she said.

The Sinn Féin leader told a packed Millennium Forum that a reunification poll is on the horizon.

"A referendum on Irish Unity will happen. It's not a question of if, but when," she declared.

She went on to propose an all-Ireland health system modelled on the NHS.

"Our system is broken. We need an Irish National Health Service. That is the future," she said.
