Opponents to Luton airport's 'MasterPlan' extension scheme claim 73% of people actually oppose the plans, contrary to the airport's claims.
Hertfordshire Against Luton Expansion, (HALE) says that the airport included a block of responses from airlines, staff and people associated with the airport to create the 65% in favour statistics, see previous story.
And they say the Government is believing what they call the airport's 'spin'.
Kathryn Hale, said: "A lot of the people in Glyn Jones' statistics who agree to it have links to the airport eg staff and stakeholders.
"In fact, 73% of the independent public oppose the plans. These plans should be called in by government as a Nationally Significantly Infrastructure Project."
These are major infrastructure developments where the ultimate decision is made by a Government Minister.
She added: "There will be nothing to stop foreign airlines using Luton, flying in their own staff to avoid tax etc. But the Government don't care. They believe Luton's spin."
Hale are opposed to the expansion plans due to noise, traffic congestion, pollution and their claim that it will export British jobs overseas.
But Luton airport just reiterated that of the 1,360 responses - 884 (65%) were in favour.
A spokesman said: "All the information is openly available from
PublicAccess v7.4 @ Luton Borough Council (Application reference: 12/01400/FUL). Table 3.1, page 6 in the 'Statement of Community Involvement' lays out the consultation response."
