Orange, which became an official partner of Paris 2024 in 2016, has joined the highest tier of domestic sponsorship of the Games in the French capital under its agreement with the Organising Committee.

French banking firm Groupe BPCE and multinational electric utility company EDF are the other premium partners of Paris 2024.

Orange will be responsible for installing high-speed broadband networks at venues due to be used at the Games.

The multinational corporation will also connect all the Games venues with fibre optic and mobile networks, according to Paris 2024.

Paris 2024 welcoming another company into its top-tier domestic sponsorship scheme represents a financial boost to organisers, who have openly warned of the impact of the coronavirus pandemic on the event in four year's time.

Reports have estimated Orange's financial investment at €144 million (£131 million/$169 million).

"We’re thrilled to welcome Orange into the wider Paris 2024 family," Paris 2024 President Tony Estanguet said. 

"Delivering the telecommunications during the Olympic and Paralympic Games is a big challenge. 

"As the event draws closer, the world’s eyes will be turning to Paris. 

"The connectivity needs to be flawless for people at the venues and online, so they can enjoy the event to the fullest, and share the excitement with others. 

"We are convinced Orange will be a great partner to tackle this challenge and create this bond. 

"Orange’s technological expertise and experience with sports events is tremendous. 

"Paris 2024 and Orange will work hand in hand to organise innovative and spectacular Games that bring people closer together."

Orange had been one of 13 official partners of Paris 2024 before upgrading its involvement with the Games.

Estanguet has claimed sponsorship revenue has already amounted to €502 million (£458 million/$589 million) from a planned €1.1 billion (£1 billion/€1.3 billion) budget.

"I’m delighted with this partnership," Paris Mayor Anne Hidalgo said.

"It’s part of an extensive team effort bringing together public and private stakeholders and aimed at making the 2020 Olympic and Paralympic Games a collective success and history making sports event. 

"The teams at the Paris City Council are fully committed to ensuring the Games provide a model for energy sobriety and set an example in terms of accessibility. 

"We have never compromised on the legacy that the Games will leave behind for everyone in the Greater Paris area, and the priorities are based on requirements for housing, transport infrastructure and sports facilities."
