Thousands of passport workers have gone on strike in a dispute over staff numbers and pay.
The Public and Commercial Services Union (PCS) said the action was a "bid to end staffing shortages that have caused the ongoing backlog crisis".
Home Office figures suggest about 360,000 passport applications are currently being processed - but it is not clear how many are overdue
The Home Office warned the PCS action could jeopardise people's holidays.
PCS spokesman, Paul McGoay, told the BBC's Richard Lister: "We believe the blame lies squarely on the government."
