Duke and Duchess of Cambridge to make Cardiff rugby visit The Duke and Duchess of Cambridge will visit Wales on Saturday, going to an oil refinery before watching the rugby. Their first stop will be to the Valero Pembroke Refinery, Pembrokeshire, which is celebrating its 50th anniversary. The couple, who used to live on Anglesey, will then head to Cardiff to watch Wales take on Australia at the Millennium Stadium. It will be their first visit to Wales since the duchess announced the couple are expecting their second child. The Pembroke refinery was opened by Prince William's great-grandmother, the Queen Mother, in 1964. It employs 1,200 people and supplies more than 10% of the UK's fuel. The couple will then watch Wales' first autumn international when the side takes on the Wallabies. Prince William is the vice patron of the Welsh Rugby Union.
