The stadium in Saint-Denis, which is set to hold more than 77,000 spectators at the Games, is scheduled to host athletics, rugby sevens and Para athletics events during Paris 2024.

However, negotiations with the Stade de France to secure an agreement on its usage for Paris 2024 were interrupted in November last year due to "substantial differences", according to a report presented by the Court of Auditors to Parliament.

The Organising Committee wants to secure usage of the Stade de France for a period of non-exclusivity from March 15 to June 1 2024, before a period of exclusivity from June 1 to September 20.

At this stage of negotiations, Paris 2024 would be expected to pay €12.6 million (£11.2 million/$13.7 million) in rent for the Stade de France and €3.8 million (£3.4 million/$4.1 million) in technical costs.

The main stumbling block is that Paris 2024 may be required to provide "tens of millions of euros" in compensation for football matches, rugby matches and concerts unable to take place during the period of exclusivity.

The Court of Auditors has urged agreements with sites intended to be used for Paris 2024 to be finalised early this year, reporting that "only 11 of the 80 user agreements planned had been signed".

It said that this represented "an operational risk and a financial risk" to the Games.

Paris 2024 has insisted that it is unconcerned at the pace of negotiations for the various venues.

"We have no concerns about our ability to sign the provisional contracts on time," it said, as reported by Actu Seine-Saint-Denis.

"The negotiation takes time because the delivery is complex.

"But we are on time."

The Organising Committee added that it aimed to secure contracts "under the best economic and operational conditions", and pointed towards agreements already reached.

"For contracts already signed, in general, between the first offer and the signature, we won between 30 and 60 per cent of the proposed price," Paris 2024 said.

The Stade de France is one of the key venues planned for usage at next year's Olympics and Paralympics.

It was built for the 1998 FIFA World Cup, and has also held matches at the 1999 and 2007 Rugby World Cups, for which it is set to be used again as a venue later this year.

The 2003 World Athletics Championships, the 2016 UEFA European Championship final and UEFA Champions League finals in 2000, 2006 and 2022 are among the other major events held at the Stade de France.

It stepped in to replace Saint-Petersburg as the host for last year's Champions League final, but the match between Real Madrid and Liverpool was marred by disturbing images and videos of bottlenecks, crushes and the indiscriminate use of pepper spray on supporters.

Kick-off was delayed by more than 30 minutes, and fans were also victims of crime outside the ground, including robberies and assaults.

The French authorities and the police were heavily criticised for their handling of the match, and it raised security concerns for Paris 2024, with a French Senate report urging relevant bodies to "draw the necessary lessons".
