The government is about to set out how it wants to change the BBC amid huge tension between the broadcaster and ministers.
The BBC is reportedly furiously lobbying to oppose changes it sees as undermining its independence and compromising its editorial and programming ahead of Thursday, when the Government is expected to announce its White Paper that sets out how it wants to change the corporation.
The White Paper on charter renewal has already prompted outrage.
"It’s not their BBC, it’s your BBC. In many ways our broadcasting - the BBC and also Channel 4, which they’re also trying to eviscerate - is the envy of the world and we should stand up and fight for it," Kosminsky told the audience.
"I think most people would agree that the BBC’s main job is to speak truth to power, to report to the British public without fear or favour.
"It’s a public broadcaster independent of government, not a state broadcaster. All of this is under threat right now.”
Ian Hislop, Private Eye editor and Have I Got News For You captain, said: "The BBC have allowed Have I Got News For You to be rude about governments... and rude about the BBC, which is a privilege you are given with public service broadcasting and not on state television."
The Culture Secretary recently joked that abolishing the BBC was "a tempting prospect".
Here are eight things the White Paper could be about to stop the BBC from doing.
Keep a huge vault of online recipes
Do lighter news stories
BBC News' domestic online coverage has been criticised for competing unfairly with under-pressure local newspapers. Lord Hall is expected to pledge to cut the lighter news items and commit the corporation to focussing more on video and a "core news service", according to The Telegraph
The paper quoted a speech by BBC Trust member Richard Ayre, who said the BBC should ditch "the magazine content, the celebrity gossip, the skateboarding ducks, the games and the puzzles to other providers, who frankly can do it just as well, or better”.

The £3.7 billion the BBC collects in licence fee payments could be shared with other broadcasters in some areas, such as children's television. This so-called 'top slicing' has triggered "a panicked and furious" lobbying effort from the BBC, The Telegraph reported

The BBC Trust (chair Rona Fairhead pictured) looks set to be abolished and replaced with a BBC Board and regulation would be handed to media watchdog Ofcom. The board's chair and vice-chair would be government appointees. In a speech in April
, journalist and broadcaster Phil Harding said this would put the BBC on "the slippery slope towards becoming a state broadcaster".
He said: "The people who are supposed to safeguard the editorial independence of the BBC – to safeguard it from, among other things, government interference – are going to be appointed by the same government that they are supposed to be protecting the BBC from."
