The application - to turn a site at the junction of Horn Lane and Western Avenue into a six-storey 100-bedroom hotel and two residential blocks of flats - received the backing of eight Labour members, while the two Conservatives voted against it at an Ealing Council meeting on Wednesday night (June 3).
West Acton Residents’ Association (WARA) and local campaigners had protested against the proposals, and held a protest at the site during a council site visit on Saturday (May 30).
Speaking after the decision, WARA's Jonathan Notley, who has now asked the Secretary of State to call in the matter, said: "We don’t think it was a fair hearing."
But Labour’s Cllr Shital Manro, who voted through the application with seven other colleagues on Wednesday (June 3), dismissed the claim and told getwestlondon the application was dealt with in "a fair and proper way".
A spokesman for the council added: “Residents can be assured that all planning applications receive a proper and unbiased hearing.
“The application will now go to the Department for Communities and Local Government.”
