Members of the public and council employees will now be able to sign the petition to save the Passport Office in some council-owned buildings.
Copies of the petition can be found in the reception areas of the Civic Centre, Newport Central Library in John Frost Square, The Riverfront and Newport Centre.
Council leader Matthew Evans urged people to sign the petition which calls on the Home Secretary to abandon the proposal to close Wales’ only passport office.
“The city council is fighting hard to keep this valuable service in our city and retain the jobs in Newport which economically makes sense,” said Councillor Evans.
A march against the closure is taking place tomorrow (Saturday). It will gather at 10.30am outside the Westgate Hotel and proceed around the city centre, past the Passport Office building, and into John Frost Square where a rally will be held at 11.45am.
