The 26-year-old was a Magpies target in January and appeared to be on a verge of a switch to St James’ Park before QPR owner Tony Fernandes managed to convince the Marseille forward to move to the west London side.
Remy went on to score six goals in 14 Premier League appearances following his £8m move but the France international was unable to help the Hoops avoid relegation to the Championship.
With the former l’OM striker managing to force his way into Didier Deschamp’s France squad in March, Remy is desperate to ensure he retains his place in the national side’s set-up ahead of the 2014 World Cup in Brazil.
A QPR statement read: “Loic Remy has joined Newcastle United on loan.
“The Frenchman, who joined QPR from Marseille in January, will remain at St James Park for the duration of the 2013/14 season.
“Remy signalled his intentions to the club earlier this summer of his desire to play in the top-flight in a World Cup year and following the recent addition of Charlie Austin to the R’s ranks, a deal has now been agreed with Alan Pardew’s side.”
QPR have been linked with a swoop for Tottenham Hotspur striker Jermain Defoe in recent days, while Redknapp signed Charlie Austin from Burnley last month.
