Surprise Kate visit marks royal farewell to Welsh home

The Duchess of Cambridge's decision to join her husband at the launch of an ultra-marathon today was a surprise and her attendance was only revealed this morning.

William said a public goodbye a fortnight ago as he confirmed his young family would be leaving their Welsh home and moving "elsewhere" when his posting comes to an end this month, having completed his three-year tour as an RAF search and rescue helicopter pilot based at RAF Valley on Anglesey.

The Duke is widely expected to leave north Wales and return to London with Kate and their baby son to take on more royal duties rather than stay in the service.
