He added: “I welcome the fact that both governments have reconvened talks under a more structured process which provides potential for a resolution.
“All parties must come to the table with a firm focus on securing a resolution to the issues we face and securing a power sharing Executive. The challenge ahead is significant but the gaps between the parties and the governments can be closed.
“Those involved in the talks, including the British Government, should be under no illusion. Confidence in our institutions and in politics is draining quickly. The public is absolutely furious and they will not accept further failure.
“The triggering of Article 50 and the stark warning of the Lord Chief Justice should focus minds in the days ahead.
“If power sharing cannot be re-established now, there is a serious threat that we’ll lose power over our affairs for a very long time.
“We cannot allow that to happen,” added the Foyle MLA.
