They say the city has a stunning creative track record and has plenty of suitable sites for a Channel 4 base.
Other competing cities include Newcastle, Coventry and Glasgow.
Yesterday, MP Louise Ellman told MPs in Westminster that Liverpool “is the right place for Channel 4″.
She said: “Liverpool is a city bursting with enthusiasm and energy. This is matched by the city’s expertise.”
“The city became European Capital of Culture in 2008 because of its achievements and potential. That was a launching pad!”
Meanwhile, more business leaders have given their support for Liverpool’s bid.
Paul Cherpeau, chief executive of Liverpool and Sefton Chambers of Commerce, said: “The chambers fully support the city’s bid to host Channel 4’s new national headquarters, which would not only create new jobs and opportunities but also celebrate the city region’s burgeoning creative and digital sectors.
“Crucially, it would help us to keep the talent nurtured through our fantastic universities and colleges in the city, supporting a more diverse and sustainable local economy. Liverpool has an outstanding pedigree in this area which would only enhance the project.”
Colin Sinclair, chief executive of £2bn regeneration scheme Knowledge Quarter Liverpool, said: “A city regenerated by culture and tourism and now powering ahead through its knowledge economy would be the perfect home for Channel 4. Liverpool is that city.
“Within easy reach of London and Manchester, and with world-leading universities producing brilliant graduates and a unique and vibrant mix of science, tech, health and cultural assets, Channel 4 would feel very much at home in Liverpool.”
Sue Grindrod, chief executive of Albert Dock Liverpool and chair of Liverpool Waterfront Business Partnership, said: “There is a natural synergy between Liverpool and Channel 4, not only through the connections with Brookside, Hollyoaks and Lime Pictures, but through the shared values between the two – both are dynamic, distinctive, inspiring and fervent champions of diversity and multiculturalism.
“Liverpool is a city that continues to embrace change and creative thinking, while retaining a strong bond to our fascinating heritage, wonderful locations and stunning architecture, which compliments the warmth of its people and the strong proud local identity. I would love to see this city become home to Channel 4’s new national headquarters.”
John Hall, chief executive of Professional Liverpool, which represents our financial and legal firms, said: “Liverpool is a natural home for Channel 4. Channel 4 changed my life – now it can change Liverpool.
“Our iconic buildings are regularly used in films, we have a thriving creative and digital sector and a proven ability to stage cultural events, as well as a waterfront to die for. How many more boxes need ticking?”
Bill Addy, chief executive of Liverpool BID Company, said: “Liverpool BID Company fully backs the city’s bid to bring Channel 4’s new headquarters to Liverpool.
“It would provide a fantastic opportunity for the city to shine on a national and international stage – we certainly have the talent and locations to support such a bid – and I am excited to see how our city centre levy payers could benefit from having one of the country’s major league media outlets located here.”
