Timeline: The Phil Gormley inquiry

9 November - The SPA and Mr Gormley's lawyers draft a press release announcing the chief constable's return to work. Meanwhile, chairman Andrew Flanagan has two meetings with Justice Secretary Michael Matheson about Mr Gormley's return - and subsequently emails board members recommending the decision is "paused". Later that afternoon Mr Gormley - on his way back to Scotland - is told by Mr Flanagan not to come back.
10 November - news breaks of a fifth complaint against Mr Gormley.
14 November - Mr Gormley's lawyer writes to Andrew Flanagan saying that "any intervention by the Scottish ministers to reverse the board's decision is ultra vires and unlawful".

30 November - Mr Gormley and Paul Johnson - the Scottish government's director of education, communities and justice - hold an "informal" meeting at St Andrews House in Edinburgh, where Mr Gormley makes clear he wants to "resume his full responsibilities as soon as possible".

23 January - As a sixth complaint is made, new SPA chairwoman Susan Deacon backs Mr Matheson's intervention, saying he would have been "failing in his duty" had he not raised questions. At the same meeting, interim police chief Iain Livingstone confirms that he was not consulted about the plan.
25 January - Mr Flanagan tells MSPs that Mr Matheson told him the move to reinstate Mr Gormley was a "bad decision" - but says the justice secretary did not seek to "direct" him. Labour calls for Mr Matheson to "consider his position".
