Britannia has been named as the filthiest budget hotel chain in the country.
The company, which has 19 properties and has been ranked as the worst hotel chain in the UK for nine years in a row, topped a ranking of the muckiest budget firms.
Britannia has by far the highest proportion of hotels scoring 3*s or less by the Food Standards Agency, according to data compiled by Property Inspect.
A quarter of the company's outlets fall below the mark.
Hygiene issues at Britannia - which lost close to £10million in the last financial year - have been well chronicled.

Last year Paul Evans, his partner and two other family members jetted back into Manchester Airport after a sunny getaway on the Greek island of Cos and headed for the Manchester Airport Inn in Wilmslow to get some sleep.
The group, from Hawick in the Scottish borders, were said they were dismayed to learn their room was not ready when they arrived at the Britannia-run establishment.
When they trouped upstairs 15 minutes later they discovered dirty bed linen dumped in the bath in a room with no sanitiser, soap or toilet roll, they claimed.
Paul, 52, and the others cleared out two hours later after lying on top of the bed fully clothed.
This year guests at the nearby The Britannia-run Airport Hotel in Manchester have slammed the "filthy" rooms after finding what appears to be "bloodstains" on the bedding.
Others who stayed there claim there was a "huge stench of cigarette smoke" and alleged their bedding had "not been changed for three weeks".
The budget hotel has faced complaints from multiple guests online, and some have claimed that they found suspicious stains on a duvet and dirt throughout their bedroom.
Those looking for a clean yet cheap room may be wise to check-in to an Ibis establishment.
Of the chain's 48 hotels, 91% have a five star rating, while just 6% are considered five stars or less.
Warrick Swift, commercial director of Property Inspect, said: “Particularly since the advent of Covid, hygiene is a much more significant public concern that is now at the forefront of a lot of our decisions, including interactions with the hospitality industry.
"For anyone planning a trip, it should be comforting to know that, for the most part, our hospitality industry is hygiene-focused, but that customers should still be mindful of these ratings when booking a place to stay.
"For these hospitality giants, there’s no reason almost 20% of properties should be receiving lower scores when there are countless ways to monitor hygiene processes and upskill staff.
"More needs to be done by industry leaders and managers to improve these ratings across the board.”
