QPR have sacked manager Neil Warnock, the club confirmed on Sunday evening.
Rangers lie 17th in the Barclays Premier League table, having won just five of their 20 top-flight games this season in their first season back in the top flight.
Warnock, who led them to the Championship title last season, has now been removed from the post, with former Fulham boss Mark Hughes strongly linked with the new vacancy at Loftus Road.
In a statement, QPR chairman Tony Fernandes, said: "This decision has been made in the best interests of the club and I can assure everyone that this is not a decision that was made lightly."
The club statement said on qpr.co.uk read: "Queens Park Rangers Football Club has today parted company with Manager Neil Warnock.
"Warnock joined the club in March 2010, overseeing 84 matches in charge, winning 33, drawing 27 and losing 24.
"Last season, he successfully guided the club back to the Premier League for the first time in 15 years.
"The board's commitment to retaining our Premier League status ultimately led to this decision. QPR assistant manager Mick Jones and first-team coach Keith Curle have also left the club."
Fernandes, who took over the club in the summer, added: "Sadly, our recent run of poor form has seen us slip alarmingly down the table and the board felt it was the right time to make a change.
"Neil has acted with honesty, professionalism and integrity throughout his time at the club, and I would personally like to thank him for his significant contribution to QPR over the last 22 months. I genuinely wish him all the very best for the future and he will always be welcome back at Loftus Road."
