British doubles players Joe Salisbury and Neal Skupski have agreed to play together on a full-time basis in the 2025 season.
Salisbury, 32, has recently split with long-time partner Rajeev Ram after winning four Grand Slam titles together.
That has paved the way for Salisbury to link up with 34-year-old Skupski, who is also a former world number one and major champion after winning the Wimbledon doubles title in 2023.
The pair represented Britain together at the Paris Olympics, losing in the first round, and also teamed up for the ATP Tour event in Madrid earlier this year.
Their full-time partnership will begin at the start of next season, which gets under way in Australia at the end of December.
Salisbury's split with veteran Ram was announced by the American earlier this week.
After linking up six years ago, they forged one of the most successful partnerships in the game.
Their first major came at the 2020 Australian Open in their second season together.
Further success came at the US Open, where they won three consecutive titles in 2021, 2022 and 2023.
Reaching world number one and winning two end-of-season ATP Finals were other measures of their success.
"Joe and I had some amazing wins, some epic matches and moments, and some gut-wrenching losses," said 40-year-old Ram.
The pair started the 2024 season by winning an ATP 250 title in Adelaide and reached the final of the Montreal Masters - a ATP 1000 event - in August.
But they could not add to their trophy haul and did not go beyond the quarter-finals in any of the four Grand Slam events this year.
The pair are ranked as the 11th best team in the world this season.
Their final tournament as a team was the US Open where, as three-time defending champions, they lost in the third round.
