Presenter Danny Baker blasted BBC bosses as "pinheaded weasels" after his popular radio show was axed, days before he is due to be honoured with a top broadcasting award.
In an online outburst he told fans his BBC London programme was being pulled, but said he had been told to keep quiet about it.
Stepping up his criticisms, he dismissed BBC claims that he was in discussions about another show, saying he had not heard anything from the corporation.
"We dwell amid pinheaded weasels who know only timid, the generic and the abacus," he said.
Baker is due to be inducted into the Radio Academy Hall of Fame later this month, one of the radio world's major accolades.
Announcing he had been axed earlier today, he told followers on Twitter: "Just been told the BBC London Show The Treehouse is to be shut down after all. Saves BBC money apparently."
Danny Baker has been axed by the BBC, ahead of his prestigious award reception next week
Two years ago to the day he announced he was diagnosed with cancer and had a period off-air while he underwent a period of treatment but bounced back to resume his presenting career. Baker - a former Radio 1 presenter - also has a show on BBC Radio 5 Live which is unaffected.
He told fans on Twitter today: "BBC asked me not to say anything just yet about axing best show on British radio. Why? Because it's embarrassing? Because they'll look bad?"
The 55-year-old went on: "Hey BBC middle management. Seriously, I'll be fine, don't feel bad."
He posted a picture of his Sony Awards and said he could sell them.
The BBC is said to have taken the decision in an effort to "refresh" the schedules.
But Baker's agent Alex Armitage claimed Baker was being dropped as a result of cuts in the budget to the local radio network.
He added: "Personally I think it is crazy. Danny is one of the greatest broadcasters in the country and this show is one of the jewels in the crown of the local radio network. I'm simply astonished."
Confirming his departure from the afternoon show on BBC London 94.9, a BBC spokeswoman said Baker would leave at the end of the year.
"Danny's still very much part of the BBC with his Saturday morning show on BBC Radio 5 Live and we're currently in discussions with him about options for a weekly programme," she added.
But Baker immediately hit back: "BBC London and I are NOT 'in discussion' about a new weekly show. In fact, I haven't heard a single word from them at all."
Comedian Rob Brydon was among those who lamented the decision to axe the show. He said sarcastically: "Glad that BBC are axing Danny Baker's daily radio show. I've had it up to here with his wit, warmth and originality."
And Baker began his programme this afternoon by playing Queen hit Radio Gaga.
Baker suggested today's programme would be his last when he came on air.
And he told listeners: "By the way, nice way to treat a bloke who had cancer."
Explaining the cancellation to the audience, he said: "Very good afternoon, everyone. As you may have heard, this show has been cancelled by the BBC. This may be the last one we ever do, but let's look past that. Nobody from the station rang me.
"No jokes, this show has been cancelled. Don't worry, I've let them know. While we can, let's huddle together like cavemen outside, sheltering for warmth. The BBC have cancelled this show for financial reasons. Don't worry, we'll keep you right across any drain blockages over there.
"They have no idea what this show does for Londoners and it's not about keeping you across the drains being blocked," Baker went on.
He said it had been an honour and a privilege to host the show for London and said he had often heard the programme helped to foster a community spirit in the city.
And he criticised the way his co-presenters Amy Lame and Baylen Leonard had been treated.
"By the way, and I hope you'll forgive me but Baylen and Amy get £50 for doing this programme. Fifty quid. I think it's fair to say that Jimmy Savile was paid more by the BBC in six months than Baylen and Amy have earned in the 10 years they have been together.
"A bit too much financial information? Well, you know what, we're cutting this down to size for you with abacuses because that's what it's about. Shame on you for what you have done to my two co-hosts."
He spent the whole of the earlier part of his show criticising the BBC, and he said that whoever had made the decision, "I hope their abacus comes undone and they choke on the beads".
Baker said he thought the cancellation was more to do with "control". He went on to criticise the station's spending on other areas and grumbled about the way the BBC had treated other well-known figures such as John Peel and Kenny Everett.Suggest a correction
