Ministers are being "misleading at best" if they claim the government has increased staffing levels in the passport service by using the last two years as a baseline, a senior Labour source has said.
"During that same time the workload has increased dramatically because of the Passport Office taking over from the Foreign Office the job of issuing passports overseas.
One of the big reasons for the backlog is that they have had a huge increase in responsibility and a decrease in staff.
According to Home Office figures, staffing levels in the passport service stood around 14% lower in 2013/14 than in the first year of the coalition government.
- 2010/11: 4,017
- 2011/12: 3,134
- 2012/13: 3,284
- 2013/14 (announced in parliament yesterday): 3,444
The Home Office has outlined how people who are facing delays to their passport renewal can get it fast-tracked for free.
