Michelle O'Neill has been officially appointed as Sinn Fein's new leader in Northern Ireland - replacing former First Minister Martin McGuinness who has stood down from electoral politics because of ill-health.
The current Health Minister's new role was announced on Monday at a Press conference at Stormont.
"In the aftermath of the election there can and will be no return to the status quo.
"It means Sinn Fein are only interested in participating in power-sharing institutions of they deliver for all of our citizens and that they operate on the basis of equality and respect," she said.
Mrs O'Neill (40), an MLA in Mid-Ulster, also paid warm tribute to Mr McGuinness and said she planned to lead the party in a similar fashion by endeavouring to break-down barriers.
