Sam Allardyce has left his position as England manager after just one game in charge, the Football Association has confirmed.
The 61-year-old, who was at the helm of the Three Lions for 67 days, has vacated his position by mutual consent after discussions with the FA on Tuesday.
Allardyce's departure comes in the wake of an investigation conducted by undercover journalists working for The Telegraph.
A report in the newspaper claimed that Allardyce had told the reporters it was possible to "get around" an FA rule, introduced in 2008, banning third parties from owning part of a player's economic rights.
In a statement released on Tuesday night, the FA said: "Allardyce's conduct, as reported today, was inappropriate of the England manager. He accepts he made a significant error of judgement and has apologised.
"However, due to the serious nature of his actions, The FA and Allardyce have mutually agreed to terminate his contract with immediate effect.
"This is not a decision that was taken lightly but... the manager of the England men's senior team is a position which must demonstrate strong leadership and show respect for the integrity of the game at all times."
The FA statement also confirmed that England Under-21 boss Gareth Southgate will take charge of the senior team for the next four matches against Malta, Slovenia, Scotland and Spain.
Allardyce, who succeeded Roy Hodgson in July following England's last-16 exit at Euro 2016 in France, becomes the national side's shortest-serving full-time manager.
