Comedian and actor Sir Billy Connolly has been knighted at Buckingham Palace for services to entertainment and charity.

The Duke of Cambridge bestowed the honour on the Glasgow-born star at a ceremony on Tuesday morning.

Connolly, also known as The Big Yin, will celebrate his 75th birthday later this year.

Speaking after the ceremony, he joked that he feared he would not be able to stand up after kneeling before the Duke.

He said: "My main worry was when I kneeled down to get the sword, would I get back up?

"Then I saw there was a handle on the stool, I thought 'oh great.'"

Earlier, Connolly said he wishes his late sister and his parents were alive to see him knighted.

He said: "My sister Flo died last year and she would have loved that, and my parents are both dead, so I wish they were here to see it."

Known primarily for his comedic performances, Connolly has also had a successful acting career, starring in the films Brave, A Series of Unfortunate Events, Mrs Brown and The Hobbit: The Battle Of The Five Armies.

In 2013, he announced he was being treated for the initial symptoms of Parkinson's disease, saying he had started to forget his lines during performances.

Connolly was in London on Monday for a Downing Street reception, hosted by Theresa May, marking 200 years since Dr James Parkinson's Essay on the Shaking Palsy.

He was joined by actress turned clinical psychologist and author Pamela Stephenson, his wife since 1989.

After learning he had been given a knighthood in the Queen's birthday honours list, Connolly told the BBC: "I am a little embarrassed but deep within me, I'm very pleased to have it.

"I feel as if I should be called Lancelot or something. Sir Lancelot, that would be nice. Sir Billy doesn't quite have the same ring."
