Cambridge dominated Oxford to complete the double as the university won both the men's and women's Boat Races on the River Thames in London.

The women's crew ensured their winning streak continued as they have now won every edition of the race since 2016.

After Oxford protests of a potential encroachment were dismissed by officials, it was confirmed that the nine-strong outfit led by cox James Trotman and stroke Caoimhe Dempsey took the win by 4 ½ lengths with a time of 20min 29sec.

The Oxford crew made an aggressive start to the 77th contest in choppy conditions but Cambridge soon wrestled control and coasted to victory.

At one point the umpire was forced to issue stern warnings to both sides as they came close to colliding before Cambridge stretched into the lead.

"That is the nature of the Boat Race," said Cambridge team President Dempsey who was the only athlete on either side that competed in last year's event.

"It makes it so exciting."

The result now means that Cambridge have won 47 Boat Races to Oxford's 30.

"That was a whirlwind of a race," Dempsey said.

"The conditions changed so much from start to finish.

"I'm so proud; it is still sinking in.

"The girls are so tenacious, strong and brave."

Cambridge's men then powered to their fourth victory in five races as they crossed the line in 16:19 to win by 1 1/3 lengths.

The mark was 1:59 away from the course record set by Cambridge in 1998 and moved the overall score to 86-81 in their favour.

Cambridge received an early warning from the umpire as Oxford pulled ahead in the opening stages.

However, a brave decision from cox Jasper Parish paid off when he steered the Cambridge boat closer to the bank in Fulham and found a smoother current.

This gave them a half-length lead which they held until the finish despite a late charge from Oxford.

"The rush of emotions when we crossed the line, there's nothing like it," said Parish, whose brother Ollie was also part of the team.

"That was the time of our lives, I'll remember this for a long time."

The end of the race was overshadowed as Oxford's Felix Drinkall was carried away on a stretcher having collapsed.

He was conscious but has been taken to hospital for further checks.
