BBC News reported that Prince William made a surprise appearance on The Graham Norton Show, and its headline begins with the word "Gasps." According to the same report, the Prince of Wales was marking his Earthshot Prize, and all of Norton's guests were linked to the prize.
The Guardian reported that William joined Cate Blanchett and Hannah Waddingham on the sofa for a special Earthshot prize edition of the show. In a report by Caroline Davies, The Guardian said the Prince of Wales has "braved the chatshow sofa" to promote his environmental initiative.
According to The Guardian, the show was pre-recorded and is to be aired on Friday on BBC One. The Guardian's summary describes the appearance as a surprise, as BBC News does.
The Guardian's summary is the only one of the two that names the guests who joined William on the sofa, Cate Blanchett and Hannah Waddingham. Both outlets tie the appearance to the Earthshot Prize, but they differ in emphasis. BBC News describes the appearance as marking the prize, while The Guardian describes it as promoting an environmental initiative. Neither summary says what that initiative involves.
The material available for this report consists of headlines and summaries only. It does not describe the exchanges between William and the guests, and it does not include any statement from the show's producers or from the Prince of Wales's office.
