Sheffield families are among the tens of thousands of people who have experienced delays in receiving new passports.
South East Sheffield MP Clive Betts said he’d had eight complaints in a month about the processing of child passports specifically.
The Home Affairs Select Committee has summoned the Passport Office’s Chief Executive to appear before them next week after widespread problems across the country.
It should take three weeks for the passport office to process applications but it is currently taking six.
Mr Betts said: “The problems and delays in processing passport applications and renewals only came to my attention because of complaints and enquiries I was receiving from constituents.
“To the best of my knowledge, the Passport Office had not made these delays public and people were still relying on the guidance to allow threw weeks for processing.
“It is now clear that there is a real danger that some individuals and families will suddenly find that they don’t have a valid passport for their holiday and business trips in the near future.”
Mr Betts advised people to apply for new passports early in the meantime.
