World number one Luke Donald will miss next week's HSBC Champions event in Shanghai to be with his wife Diane for the birth of their second child.

A statement from the tournament organisersexternal-link explained that the Englishman, who had "reluctantly" made the decision.

"It's important to make sure that I'm around to support my wife," he said.

"The birth of our first daughter inspired me to some really great golf."

Donald, who clinched the PGA money list by winning the Disney Classic, is aiming to be the first player in history to win United States and European money lists in the same season.

It was hoped his second daughter would arrive this week but he was eventually forced to make the decision to pull out of the $7m (£4.3m) event in China.

"Family does put a lot of things into perspective; my job is very important but the family out-trumps everything," he added.

With just five weeks remaining on the European Tour schedule, Donald currently leads the Race to Dubai by over 1.3 million euros (£1.1m) from Rory McIlroy.

He has previous form in Shanghai after finishing third at the event last year.

He came in 10 shots behind winner Francesco Molinari and nine behind fellow Englishman Lee Westwood, as the Italian won his first WGC event.
