William, 88, is the longest-serving soap star in the world having played Ken Barlow since the show started in 1960.
Corrie has also been awarded a new certificate from Guinness World Records confirming it remains the world’s longest-running TV soap. William said: “I have been very fortunate to have been in this wonderful programme, which has carried me into this world record and a lifetime of wonderful memories.”
Corrie producer Iain MacLeod said: “Bill’s is a singular, spectacular accomplishment. I heartily congratulate him for his peerless professionalism, unstinting commitment to the show and brilliance as an actor.”
He went on to add: “It is an incredible achievement, a testament to Tony’s instincts as a dramatist and proof that the characters and narrative universe he designed are still as relevant today as they were then.”
William will be at the heart of on-screen events for the 60th anniversary episode in December.
The show which was originally scheduled to run for just 13 weeks was presented with an updated certificate marking the achievement for the cast and crew.
Meanwhile other Corrie stars have been busying themselves with home decor throughout the lockdown.
Actress Catherine Tyldesley has turned her mind to home interiors like a great deal of Britons, and is getting her kitchen completely refurbished.
The 37-year-old recently took to Instagram to show her 631,000 followers the snazzy space which looks set to be very modern and impressive.
Donning a gorgeous brown jumper and stylish coat with her brunette locks in loose curls, the star stood in the kitchen and said: “Hey guys, just a little update on the kitchen.
“As you can see it’s progressing. I’ve got the ovens in, got the microwaves in, got the posh coffee machine in. It’s too exciting.”
While telling fans what had been done so far, Catherine panned the camera around to face the state-of-the-art kitchen appliances which had been fitted, revealing stunning matte black cabinets.
Coronation Street continues on Friday at 7.30pm on ITV.
