Martin McGuinness has announced his resignation as Deputy First Minister of Northern Ireland in protest at the Democratic Unionist Party's handling of a botched renewable energy scheme.
The Sinn Fein veteran's move, which will come into effect at 5pm on Monday, is likely to lead to a snap Assembly election in the region.
Mr. McGuinness announced his decision after his partner in government, DUP First Minister Arlene Foster, repeatedly refused to step down to facilitate a probe into the ill-fated Renewable Heat Incentive (RHI) - a scheme that has left Stormont facing a £490 million overspend.

Impartial Reporter: Enterprise Minister Arlene Foster has responded to claims made in a BBC documentary.

Mr. McGuinness said he was resigning with "deep regret and reluctance".
"The First Minister has refused to stand aside, without prejudice, pending a preliminary report from an investigation.
"That position is not credible or tenable."
He made clear that Sinn Fein would not replace him in the role.
As a consequence, the collapse of the institutions and an election are now inevitable.
"We now need an election to allow the people to make their own judgment on these issues democratically, at the ballot box," he said.
Earlier Mrs. Foster told The Impartial Reporter that if Sinn Fein was “playing a game of chicken” by calling for her to step aside over the flawed renewable heat incentive scheme then “they are wrong.”
