Sue Barker all smiles as she leads Wimbledon celebrity arrivals days after slamming BBC over axe of co-star

Mr Castle learned of the decision before the Championships began and will provide commentary throughout the fortnight for one final time.

Ms Barker told The Telegraph: "I'm sad that this news has come as a bit of a shock to him, but it feels that way for all of us, because we love what we do so much."

The pair's professional relationship stretches back more than three decades to when Ms Barker was beginning her career at Sky TV.

Ms Barker praise for Mr Castle went on: "As a presenter, I always loved having Andrew in the studio, because he offered something a bit different."

Mr Castle, 62, also told The Telegraph he would have preferred to depart on his own terms, a privilege that Ms Barker herself was granted four years ago.

The commentator expressed particular regret that he will miss reaching a significant milestone with the broadcaster.

"Am I upset? Yeah, I was upset, and I will stay that way this year, knowing it's my last," Mr Castle said.

"But all good things come to an end. It would have been my 25th year. But who's bleating?"

He acknowledged the manner of his departure was handled appropriately, noting he was informed face-to-face and in a respectful fashion.

Elsewhere, several other famous faces followed Ms Barker to take in the second day of the annual tennis tournament.

Radio 1 DJ Greg James looked smart in a chino and jacket combo, while Richard Osman waved to onlookers as he made his way inside.

Sir Cliff Richard stepped out for the second time in as many days, smiling at fans at the grounds.

England cricketer Stuart Broad arrived at Wimbledon hand-in-hand with Saturdays singer and wife Mollie King.

Meanwhile, actress and presenter Jameela Jamil and classical singer Katherine Jenkins both arrived in shades to combat the south-east London sun.

Footballers Maya Le Tissier and Freya Godfrey were also among the early arrivals.
