Venus and Serena Williams have qualified for a fourth family tennis final in the women's singles at Wimbledon.
Venus's place in an eighth Wimbledon final was never in doubt as she dispatched world number one Dinara Safina 6-1 6-0 in 51 minutes on Thursday.
But her younger sister's match with Elena Dementieva lasted three sets and two hours 48 minutes before Serena won 6-7 (4-7) 7-5 8-6.
The match was the longest women's semi-final in recent Wimbledon history.
The pair will meet on Saturday in their fourth Wimbledon final when Venus will seek her sixth title and Serena her third.
