Talksport phone-in host Mike Dickin, known to listeners as "The King", has died in a road accident in Cornwall.
The presenter, who was in his 60s, was involved in a six car pile-up on the A30 on Monday. He was airlifted to hospital but was pronounced dead.
Dickin started his career at BBC Radio Oxford in the 1970s, where he was the first presenter on the air.
He also broadcast on Radio 4 and LBC, and won an award for his coverage of the Lockerbie disaster in 1988.
The presenter, who broadcast from his home studio in Bodmin Moor, was known for his passionate, outspoken views.
Listeners dubbed him Britain's angriest man, but he was also known as "The King" because of his supposed resemblance to Henry VIII.
Dickin hosted weekend overnight phone-ins on Talksport and was last heard on the station last weekend.
Colleague James Whale paid tribute to the broadcaster, calling him "the original grumpy old man".
"Radio will never be the same again," continued the presenter, who will pay tribute to Dickin in his programme on Thursday night.
