Director of rugby Jim Mallinder has left Northampton Saints with immediate effect.
The news comes after a dismal run of form from the Saints and follows Saturday’s 42-32 defeat to the Ospreys in the Champions Cup.
It was their eighth straight defeat across the Premiership and Europe’s top competition.
Alan Dickens, the club’s attack coach, has taken over on an interim basis.
“Jim has been an outstanding director of rugby. We have been very lucky to have him at Franklin’s Gardens and he will always be a part of the Saints family,” said John White, Northampton Saints chairman.
“This is not a decision that has been taken lightly, but the board and major shareholders felt that the time was right for some change.”
Mallinder took over Northampton in 2007 following their relegation to the second tier of English rugby. They were promoted back to the top flight at the first time of asking and won the Premiership title in 2014 having lost the final the previous season. Mallinder also led Northampton to the European Challenge Cup in 2009 and 2014, and the Anglo-Welsh Cup in 2010.
But recent form has seen Northampton’s board call an end to his 10-year spell at the club.
The Saints will now start their search for a “world-class director of rugby” to replace Mallinder but in the short-term will bring in “additional leadership” to their coaching team, according to White.
