A petition signed by more than 100,000 people calling for a debate on changes at Ealing Hospital was signed by less than 1,000 people in the borough, figures reveal.
The data shows signatures from all over the country made up the petition by campaigners.
Ealing Central and Acton MP Rupa Huq, Ealing Southall MP Virendra Sharma and Hammersmith MP Andy Slaughter criticised changes at Ealing Hospital and urged reconsideration during a debate at Westminster Hall on Wednesday (May 3).
The debate was held after Mr Sharma has applied for one through a ballot in response to the petition titled 'SAVE OUR NHS STOP PRIVATISATION SAVE EALING HOSPITAL Publicly Funded & Provided'.
But according to figures from the House of Commons Petitions Committee, fewer than 1,000 of the signatures came from people who live in Ealing out of the total 100,229 who signed it.
Of the total, 58 came from Ealing Central and Acton, 321 from Stephen Pound MP's Ealing North constituency, and 574 from Ealing Southall.
But Mr Sharma argued the figures reflect how the debate was not just an issue for Ealing, but was a matter for the whole country.
He added: "Threats to healthcare services affect everyone, so this isn't just an issue for people in Ealing.
"SaHF is a test case and what happens here could happen across the country.
"That people from Falkirk to Falmouth signed the petition shows that the NHS is a national treasure and not something that this government can toy with.
"A previous petition organised by Ealing Council in 2012 had over 80,000 signatories, most of whom were local residents."
The petition was launched by Save Ealing Hospital Community Action Group (SEHCAG) on November 12 last year.
