Michel Platini, the former Uefa president, has insisted his conscience was clear after he was questioned by detectives over controversies surrounding the awarding of the 2022 World Cup to Qatar and Euro 2016 to France.

The ex-France captain, who was also a vice-president of Fifa at the time, was taken into custody and quizzed along with two former aides to Nicolas Sarkozy as part of a wide-ranging investigation into football corruption by French officers.

The Anti-Corruption Office of the Judicial Police (OCLCIFF) is understood to be investigating whether the then French President had any influence in Platini's apparent change of mind in voting for Qatar instead of United States as a host nation in 2010. Two weeks before the 2022 World Cup vote in 2010, Mr Sarkozy hosted a lunch for Qatar’s leaders with Platini.

A spokesman for Platini, who claimed he had not been arrested but was instead "questioned under the regime of custody for technical reasons", confirmed he was also asked about the decision to award the European Championships to France.

Before the bidding process for the Euros, Platini reportedly introduced Mr Sarkozy to every member of the decision committee in person.
