Northern Ireland's parties have failed to reach agreement in the talks to restore power-sharing at Stormont.
The deadline for a new Executive was 4pm on Monday, but a scheduled sitting of the Assembly was cancelled after negotiations broke down.
It meant a new first and deputy first minister could not be noniminated.
All eyes will now be on Secretary of State James Brokenshire who must decide the way forward - with options including further talks, another snap election, or direct rule being reimposed from Westminster.
So if the Assembly doesn't sit it means no FM/dFM will be elected & at 4pm it's over to @jbrokenshire
The DUP is prepared for another election if an agreement cannot be reached in the talks process, Sir Jeffrey Donaldson has said.
Irish speakers have welcomed DUP leader Arlene Foster’s pledge to better understand the language.
Alliance leader Naomi Long has said the devolution project could be lost because of the lack of trust between the parties.
