Sir David Attenborough and David Beckham among stars at Wimbledon

Sir David Attenborough appeared in good spirits as he arrived in the royal box on Centre Court on the first day of Wimbledon .

The 98-year-old broadcaster and naturalist smiled broadly as he arrived, wearing a navy blue jacket and patterned tie, with his daughter Susan.

He shared a laugh with footballer David Beckham , who was in attendance with his mother Sandra.

Beckham, dressed in a beige jacket and brown tie, also appeared in a jovial mood.

Other stars watching the first day of the championships included opera singer Katherine Jenkins and Pointless star Alexander Armstrong.

Jazz singer Jamie Cullum was also focused on the action as he watched the tennis from the royal box, alongside Play School’s Baroness Floella Benjamin and her husband, Keith Taylor.

Emma Raducanu and defending men’s champion Carlos Alcaraz are highlights of the opening day at the All England Club.

Alcaraz is playing Estonian Mark Lajal while former US Open champion Radacanu was handed a Wimbledon boost on Monday morning when scheduled opponent Ekaterina Alexandrova withdrew through illness.

She will now take on Mexican Renata Zarazua on Centre Court.

Meanwhile, Andy Murray will make a decision on whether to play singles in the tournament after a practice session on Monday afternoon.

The 37-year-old underwent surgery to remove a spinal cyst nine days ago.

He showed signs of improvement hitting against fellow British player Kyle Edmund but remains unsure whether he is in good enough physical shape to play his first-round match against Czech Tomas Machac on Tuesday.
