Prince Andrew says he "ceased all contact" with a businessman accused of being a Chinese spy after government advice and that "nothing of a sensitive nature ever discussed".

Niall is joined by our royal correspondent Rhiannon Mills and our home editor Jason Farrell to explain how the story unfolded, what the wider implications are for the UK and what Prince Andrew's involvement is.
