later cleared of any wrongdoing. It was later claimed that key evidence thought to have been retracted had not been withdrawn, prompting several Falkirk councillors to urge Miliband to publish details of the party's internal inquiry or to hold a fresh investigation. On the 4 November edition of Good Morning Scotland, Lamont said there was a case for a fresh inquiry, but that Labour does not publish details of its internal investigations. Later the same day, Labour said that it would not be reopening the investigation. Miliband subsequently said that a new investigation was unnecessary. On 8 December the former MSP Karen Whitefield was selected to contest the seat. The report into Labour's inquiry was leaked to the media in February 2014, and concluded there was "no doubt" that Unite had attempted to manipulate the selection process. In October 2013 Lamont faced criticism for her reaction to an industrial dispute at the Grangemouth Oil Refinery. Ineos, the company that operates the plant, had stated that the refinery was making financial losses, and had proposed a survival plan requiring employees to accept worse employment terms, notably changes in work rules and less generous pensions; this the employees rejected. The company mothballed the plant, threatening to close it if the terms were not accepted. Lamont urged Ineos to withdraw its conditions and for both sides to hold talks, while Salmond tried to negotiate an agreement. Union officials eventually agreed not to call a strike for at least three years, and the plant reopened. The Ineos chairman, Calum MacLean, described Lamont's support for the trade unions during the dispute as "deeply irresponsible", while Salmond claimed she had been silent throughout the disagreement. Writing for the Dunfermline Press, Natalie McGarry suggested that while the Labour leader's silence probably had much to do with the continuing Falkirk selection row, ultimately she was "found wanting". Resignation Scotland voted by a 10% margin against independence, but the referendum returned "Yes" votes in some traditional Labour strongholds, particularly Glasgow and North Lanarkshire, prompting media speculation about Lamont's future as the party's leader. Shortly after the referendum, Shadow International Development Secretary Jim Murphy was discussing taking over from her, while The Herald reported that party delegates concerned about the results had started to view Murphy as a possible successor. Lamont had attempted to quash rumours of a leadership challenge at the 25 September 2014 session of First Minister's Questions,
