Emma Raducanu’s shot at US Open glory will be available to watch on free-to-air television after Amazon Prime agreed a deal with Channel 4 to share the women’s final on Saturday.

The 18-year-old has captivated the nation with her exploits in New York and she takes on fellow teenager Leylah Fernandez in the showpiece event hoping to become the first British woman to win a grand slam in 44 years.

Amazon’s Prime Video streaming service has had exclusive broadcast rights in this country for the final grand slam of the year, but has agreed a deal – understood by the PA news agency to be seven figures – for the match to be shown on both Prime Video and Channel 4, maximising the viewing potential for one of the biggest sporting stories of the year.

Oliver Dowden, secretary of state for culture, media and sport, praised the deal.

His statement read: “Tonight the whole country will be behind the British tennis sensation Emma Raducanu, so I am delighted that Amazon Prime and Channel Four have responded to our call to make this historic sporting moment free to watch so that as many of us as possible can cheer her on tonight.

“I applaud them for their quick work in making this happen and for the fact that the money involved in this deal will go direct into women’s tennis in Britain to benefit and inspire the stars of the future.”
