Portsmouth have confirmed that former Chelsea manager Avram Grant will be taking over first team affairs following the sacking of Paul Hart.
Chief executive Peter Storrie said: "Avram is a very experienced and respected manager who has managed at the highest level.
"The board believes he is the man to help steer the club out of the relegation zone.
"He knows the club, the players and the set-up at Fratton Park, so it was the logical move to make him the next manager, once the board had decided to relieve Paul Hart of the role.
"He will take charge of training on Friday alongside first-team coaches Paul Groves and Ian Woan."
