The passport backlog has lead to a shocking mistake - which could scupper one woman's holiday plans. The Passport Office, which has been overwhelmed by applications in recent weeks, returned Natalie Peel's passport to her this week - with another woman's photograph.
And she's not the only person to have discovered mistakes during the recent crisis.
Natalie Peel, a 27-year-old teacher from Bacup in Lancashire, had recently married, so sent her passport off to be renewed and have her name changed. She thought she'd left plenty of time, because she sent it on 27 June and was only set to travel in August.
However she told the Daily Mail that her passport arrived back at the beginning of July, featuring another woman's photograph alongside her details. She said: "It's disgraceful, especially when you put a certain amount of trust in the government.... I sent my details in confidence and I expect them to be handled securely. God knows where my picture has ended up". She added that she was worried whether there would be time to correct the mistake before she was due to travel.
And Peel isn't the only victim of a mistake by the Passport Office during this crisis.
Last week it emerged that Barbara Cheeseman, of Kingswood, Bristol, had received two passports. She applied on 27 May after her husband's father fell ill in Cyprus, and received the first passport last week. Then a day later her husband received his passport - and she got a second one - with a different number. The couple told the Bristol Post that they were confused because they didn't know which was the legitimate passport.
Shadow Immigration Minister, David Hanson added that there were security concerns. He said:"It is extremely worrying. We have had examples elsewhere in the UK recently of people being sent the wrong passport and it shows that the Passport Office is under tremendous pressure at the moment and I will be asking the Home Secretary again on Monday at Parliamentary questions to investigate this type of incident."
A few days earlier a woman in Broughton in Wales received a passport, visa documents and birth certificate belonging to a Pakistani man from Lancashire. She said she hadn't been able to report the mistake because the Passport Office wasn't answering their phones.
Those who are facing mistakes, or long delays that leave them in fear of missing their holiday, will take no comfort from the fact that in some cases when passports finally arrive, they aren't being checked properly. Pauline Briggs from Kiveton Park, Rotheram, has hit the headlines after accidentally using her late husband's passport. The 64-year-old went through two security checks at East Midlands Airport before arriving in Fuerteventura where the mistake was discovered. Fortunately she was allowed into the country and arranged a temporary passport for her return.
