UEFA's executive committee has given the green light to holding the European championships in 2020 across the continent, the ruling body's secretary-general Gianni Infantino said on Thursday.
Former French captain Michel Platini, who is president of UEFA, first mooted the idea of holding the tournament in a number of cities earlier this year, as a way of avoiding high costs at a time of dire financial constraints in many countries.
"UEFA Euro 2020 will be staged across the continent, in various major cities, following a decision taken today," said Infantino, calling the tournament in eight years' time "A Euro for Europe".
"The response has been extremely positive from all the national associations, he added, apart from Turkey.
Infantino said he was not in a position to say how many countries and cities would be involved but if the project was ready in January, it would be rubber-stamped then or at the executive committee meeting on March 23.
Cities were likely to be chosen in early 2014 -- six years before the start of the tournament, he added.
Turkey, which has put itself forward as a candidate for 2020 alongside Azerbaijan and Georgia and a three-way bid from the Republic of Ireland, Wales and Scotland, was the only country opposed to the project.
Istanbul is also a candidate to host the Olympic Games in the same year, although the International Olympic Committee (IOC) has said that having one country host two major events so close to each other is against its rules.
FIFA secretary-general Jerome Valcke, speaking in a personal capacity, said last week that he failed to grasp the concept of a continent-wide tournament, saying it would destroy the competition.
Platini said before the eve of this year's Euro finals that the 60th anniversary of the competition, which is held every four years, could involve "12 or 13 cities across Europe" and that most of the 53 UEFA federations were in favour.
Central to his argument was that it would make organisation easier, after serious concerns about cost overruns and infrastructure delays in this year's hosts Poland and particularly Ukraine.
This year's competition was the first time that the championships had been held behind the former Iron Curtain and the decision for the 2020 tournament also breaks new ground.
Euro 2016 is scheduled to take place in 10 cities across France but there are already concerns about the progress of new or refurbished grounds, particularly in the northern Lens and eastern Lyon.
The draw for the qualifying campaign for Euro 2016 will take place in the Mediterranean city of Nice on March 9, 2014.
The qualifying phase for the tournament will run from September 2014 to November 2015.
The venue for the final has not yet been chosen, although it is likely to be held at the Stade de France, in Saint-Denis, just north of Paris and scene of France's 1998 World Cup triumph over Brazil.
