Northern Ireland First Minister Peter Robinson steps down: Timeline of events
Stormont First Minister and Democratic Unionist Party leader Peter Robinson has announced he is to 'step aside' and that party colleague Arlene Foster is to take over as temporary First Minister.
Here is a timeline of significant events over the past five months.
- May 5 - Mr Davison, 47, is shot dead at Welsh Street in the Markets area of Belfast. The senior republican backed Sinn Fein's peace process strategy following the 1998 Good Friday Agreement and was employed as a community development worker in his local neighbourhood. He was linked to the 2005 fight which led to the death of father of three Robert McCartney in one of Northern Ireland's most notorious killings, but was never charged. His uncle, Terrence Davison, was later acquitted of the murder.
- May 9 - Funeral for Mr Davison is attended by a number of high profile republicans, including Bobby Storey, Eddie Copeland and Brian Gillen. His coffin is draped in an Irish tricolour with a beret and gloves placed on top.
- May 12 - The Police Service of Northern Ireland (PSNI) say murder investigation is "challenging", but rule out dissident republican or loyalist paramilitary involvement.
- May 26 - Police reveal an unusual Eastern European weapon was used in the shooting.
- August 12 - Former IRA man Kevin McGuigan, 53, gunned down close to his home at Comber Court in the Short Strand area of east Belfast. Mr McGuigan and Mr Davison had been embroiled in a long-running personal feud and he had been suspected by many within the republican community of involvement in May's murder. There is widespread speculation that Mr McGuigan was killed in a revenge attack carried out by Mr Davison's IRA associates.

- August 20 - PSNI Detective Superintendent Kevin Geddes says he believes Provisional IRA members were involved in the murder of Mr McGuigan alongside Action Against Drugs (AAD) - a group that includes former IRA members, dissident republicans and criminals. Sinn Fein president Gerry Adams rejects allegations of IRA involvement in the shooting and insists they left the stage in 2005. Mr Robinson reiterates his warning of Sinn Fein expulsion. One of the arrested men - Patrick John Fitzpatrick, 53, from the Lagmore area of Belfast - appears in court charged with possession of a weapon with intent to endanger life. The others detained were released.
- August 22 - PSNI Chief Constable George Hamilton says the IRA still exists, but is not on a "war footing". Following crunch talks with political figures at PSNI headquarters, Mr Hamilton says IRA are committed to "promoting peaceful political republicanism".

They bring to 16 the number arrested over the murder. Fitzpatrick remains the only person charged with any offence.

Prime Minister David Cameron appeals to Northern Ireland's political leaders to work together as they did during the peace process.
