The manager of the English football club Portsmouth, Paul Hart has left the Premier League's basement club with immediate effect.
The club says the decision to relieve him of his duties had been "made reluctantly based on results that leave Pompey at the bottom of the league".
Hart was offered a role as technical director responsible for players aged 18 to 21, but declined it.
Coaches Paul Groves and Ian Woan take temporary charge, with director of football Avram Grant tipped to be boss.
Former Chelsea boss Grant returned to Pompey in October, but the Israeli is currently awaiting a work permit and has yet to formally take up his duties.
Hart took charge following the sacking of Tony Adams in February 2009.
He kept Portsmouth in the top flight last season, but they have taken just seven points from 13 league games so far in the current campaign.
