The French Grand Prix, which returns to the F1 calendar for the first time since 2008, is to have Pirelli as its title sponsor.

Though the 2008 race was held at the Magny Cours track, Paul Ricard, which hosts this year's race, last hosted the French Grand Prix in 1990.

Confirming the deal, which will see the event named the Formula 1 Pirelli Grand Prix de France 2018, Pirelli's Mario Isola said: "We're very proud to be at the forefront of the return of the Formula 1 Pirelli Grand Prix de France 2018.

"F1 is an extraordinary platform for research and development for our technical teams," he continued, "but also a wonderful communication tool. As France is one of the biggest markets, it was key for us to reinforce our visibility and our presence on the circuit and the paddock. The French round at Le Castellet will be an important moment in the 2018 season and Pirelli is happy to be part of it as a title sponsor."

Meanwhile, Singapore Airlines has extended its title sponsorship of the Singapore Grand Prix for another two years. The airline first signed as title sponsor in 2014, initially for two years, though this was subsequently extended for the 2016 and 2017 races.

"The Singapore Night Race is the highlight of Singapore's sporting calendar and we are thrilled to continue as its title sponsor," said said Singapore Airlines CEO, Mr Goh Choon Phong. "We look forward to showcasing this event to the world and enhancing both tourism and sports for the benefit of Singaporeans and visitors alike."

"F1 is delighted to extend its relationship with Singapore Airlines," added F1 Chairman and CEO, Chase Carey. "The strength of Singapore as a destination is an example of the excitement F1 is creating around the globe and having prestigious partners such as Singapore Airlines shows our ambitious vision is shared by the market leading companies around the world."

"We are delighted to have Singapore Airlines partner us once more as title sponsor," said Singapore GP Pte Ltd Chairman, Mr Teo Hock Seng. "The partnership over the last four years has been a key component in the success of the night race. As we embark on the next chapter with Formula 1, we look forward to harnessing our combined reach and brand recognition to showcase the very best that Singapore has to offer."
