Campaigners against plans to house asylum seekers at a military barracks have dismissed reports the scheme could be delayed and say they could seek judicial review this week.
Crowborough training camp is earmarked by the Home Office as a possible location to house 540 lone male migrants.
Residents of the town took to the streets for the fourth weekend running to demonstrate against the plan, despite the scheme facing delays.
The Home Office said while it was still “continuing to accelerate plans” to move asylum seekers to the Crowborough military base it would wait until it was “fully operational and safe”.
Buses were expected to start arriving in Crowborough with asylum seekers on Monday.
Campaigners have so far raised more than £50,000 to fund their legal challenge against the plan which they believe is still going ahead.
Chairwoman of Crowborough Shield Kim Bailey described reports of delay as a “smokescreen”.
“This is what they want us to believe so we let our guard down,” she told marchers on Sunday.
Around 2,000 people braved the cold on Sunday morning to march from the camp to a village green where they were told an application from Crowborough Shield for a judicial review could come this week.
“We think December 3 will be the day they move in,” said Ms Bailey.
“Please, don’t let your guard down.
“The reports of a delay is what they are trying to make us think.
“We need to get this in front of a judge.”
Protesters who marched from the camp on Sunday morning past council offices chanted: “Shame on you.”
The crowd demanded the resignation of Councillor Rachel Millward.
The deputy leader of Wealden District Council is also deputy leader of the Green Party and the party’s candidate for the mayor of Sussex and Brighton.
The crowd also chanted: “No accommodation, deportation”.
Organisers say they will march every weekend until the Home Office plan is abandoned.
