Thousands of Brighton and Hove Albion fans will march on the Labour Party conference with a final loud and clear message to John Prescott.
The Deputy Prime Minister has promised the Seagulls a decision on the long-running Falmer stadium saga by October 31.
His ears will ring with the chants of a sea of blue and white as he deliberates.
The march will take place on September 26, the first day of the conference, at 5pm. It will start at the Volks Railway and finish on the seafront opposite the Brighton Centre.
Albion chief executive Martin Perry said: "The inspector's report from the second public inquiry into our new stadium is now in John Prescott's office and his advisors are looking at it.
"That means there are only a few weeks to go before we know whether or not we have planning permission to build our stadium at Falmer.
"This is our last chance to get our massage across and we want as many fans as possible to come out and march to the conference.
"The bigger the turnout, the stronger the message.Let's show John Prescott we mean business."
Several thousand fans took part in a similar march at last year's conference.
Mr Prescott has praised the light-hearted and non-confrontational style of the Falmer For All Campaign and acknowledged the need for a stadium in Brighton and Hove.
The public inquiry was reopened to determine whether there were any viable alternative sites to Falmer for the 22,000-seat stadium.
The club first identified Falmer as its preferred site in 1999. Its application is backed by Brighton and Hove City Council and The Argus and won overwhelming support in a city-wide referendum.
Albion chairman Dick Knight said last month he hoped Mr Prescott would make his decision before the conference so fans could give him a hero's welcome to the city.
The Falmer For All Campaign delivered a giant postcard to his constituency office when Albion took on Hull City last month.
Mr Perry said: "The waiting has gone on long enough. It is time for the development to go ahead."
The march has been agreed with Sussex Police, who are planning the tightest security operation ever seen in Sussex during conference week.
