The Williams sisters will compete in the final of Wimbledon for the fourth time.

Serena Williams, who has two Wimbledon trophies to her name, booked a place in the final with a 6-2 7-6 victory over Chinese wild card Zheng Jie on Centre Court.

Serena won the first set in 28 minutes after breaking Zheng's serve in the opening game.

Zheng forced a tie-break in the second set but double-faulted to give Serena victory.

Four-times champion Venus had already reached her seventh final with a 6-1 7-6 win over Russian Elena Dementieva in the first semi-final.

Serena said: "(Venus) is a tough opponent, the toughest I've played here but we're going to stop talking to each other until the final."
