The Committee claimed it wanted "more precise information" about the overall cost of the Games and the schedule of work, with special rapporteur Éric Jeansannetas claiming there are "risks" surrounding delivery.

He said equipment which budget documents say will be received this year has now been pushed back to 2024.

This includes at venues such as the Stade de France, the Arena Porte de la Chapelle, the Grand Palais, the Athletes' Village and the marina for sailing in Marseille, it is alleged.

The Grand Palais, which is due to host fencing and taekwondo, is claimed to be facing "significant delays" and is the "greatest concern", according to Jeansannetas.

"These uncertainties are regrettable, as we reach the home stretch of preparation for the Games," Jeansannetas said, while claiming that the situation is "not reassuring" as delays could mean extra costs.

Solideo claimed, that out of the 70 structures and sites for which it is responsible, there had been "no change in the contractual delivery dates with the organisers".

"We have no delays in terms of construction," a statement sent to insidethegames said. 

"We have different stages between reception of the sites - which means the end of the construction works - and delivery to the organisers, which comes later. 

"And it is this that can perhaps create confusion." 

According to Jeansannetas, costs relating to security and transport are also unknown.

The Olympics in Paris are due to run between July 26 and August 11, followed by the Paralympics from August 28 to September 8.
