LONDON, England (Reuters) – Russia’s Dinara Safina was confirmed as world number one in the WTA rankings published yesterday to complete a famous double for her family.

Safina, 23 next Monday, was assured earlier this month of becoming the 19th world number one since the rankings started in 1975 and she is the second Russian to hold the position after Maria Sharapova.

Sisters Serena and Venus Williams have both held top spot but Safina’s ascent makes it the first time a brother and sister have led the rankings. Marat Safin first became men’s world number one in November 2000.
