Prince William sings along to Welsh national anthem as he cheers them on at Rugby World Cup - after Kate made a solo trip to watch England play

Prince William, 41, was among the 42,000 crowd to watch Warren Gatland's men take to the pitch during their opening Pool C game. Wearing a red tie with white stripes, the future King was on his feet bellowing out with pride the words in Welsh to Hen Wlad Fy Nhadau - Land of Our Fathers. William, patron of the Welsh Rugby Union, was seen laughing and joking as he sat alongside Gerald Davies, the 50th President of the Welsh Rugby Union. William gave a sideways glance as his image appeared on the big screen. But it appeared his face was not greeted with the same rapturous applause and cheers which erupted for Kate Middleton when her face was shown to the crowd 24 hours earlier as she watched England take on Argentina.
