Sunderland have appointed Paolo Di Canio as their new coach on a two-and-a-half year deal.
Di Canio will take charge from tomorrow after travelling to the north east today for talks.
The 44-year-old Italian replaces Martin O'Neill who was sacked following yesterday's 1-0 defeat at home to Manchester United, which left the club a single point above the relegation zone.
Di Canio's appointment immediately prompted British politician David Miliband to resign his post as vice-chairman and non-executive director of Sunderland due to the Italian's "past political statements".
The former British foreign secretary made the announcement on his personal website, www.davidmiliband.net.
Miliband said: "I wish Sunderland AFC all success in the future. It is a great institution that does a huge amount for the North East and I wish the team very well over the next vital seven games.
"However, in the light of the new manager's past political statements, I think it right to step down."
Di Canio has admitted to having fascist leanings, telling Italian news agency ANSA in 2005: "I am a fascist, not a racist."
The Italian, who has not managed at Premier League level before, has also courted controversy most recently following his acrimonious departure from League One club Swindon in February.
Despite that Sunderland chairman Ellis Short believes the former West Ham forward is the man to steer the Black Cats away from the relegation zone.
"Paolo is hugely enthused by the challenge that lies ahead of him. He is passionate, driven and raring to get started," he said in a statement on the club's official website.
"The sole focus of everyone for the next seven games will be to ensure we gain enough points to maintain our top-flight status.
"I think that the chances of that are greatly increased with Paolo joining us.
"Our fans have shown tremendous patience and understanding this season. They have continued to back the team in huge numbers, both home and away, and that is something that continues to inspire all of us in our drive to give them the successful club they deserve.
"That remains our primary aim."
Di Canio's only managerial experience came during a tumultuous 18-month stint at Swindon, which was highlighted by helping the club to promotion back to League One last season.
The Italian also grabbed the headlines for occasional outbursts against some of his players, but despite those moments the club had continued to prosper under his leadership this season.
The Robins were challenging for back-to-back promotions before his sudden departure in February.
Di Canio cited "broken promises" from the Swindon board as the reason for his decision adding also that he had "delivered everything and more that was asked of me".
His first game in charge of Sunderland will come against Chelsea at Stamford Bridge next Sunday, followed by a Tyne-Wear derby against fierce rivals Newcastle at St James Park a week later.
The Italian has seven games to save Sunderland from the drop but inherits a team that is without a league win in eight games, taking three points in that time.
