Welsh Rugby Union (WRU) Chief Executive Roger Lewis will leave his post after this year's World Cup, the WRU announced Tuesday.

Lewis, 60, has been in the job for nine years and will stand down on October 31.

During Lewis' tenure, Wales have won three Six Nations titles, including two Grand Slams, and also reached the 2011 World Cup semifinals, their best performance in the competition since 1987.

Lewis was also responsible for the appointment of New Zealander Warren Gatland as Wales head coach in late 2007, with spectacular results as Wales achieved the Grand Slam in 2008.
