Arlene Foster

In September 2007, a privately financed proposal for a new Giant's Causeway centre was given preliminary approval by Foster in her role as Northern Ireland Environment Minister.[15] Immediately afterwards, the public money that had been allocated to the causeway development was frozen. The proposal resulted in a public row about the relationship between the private developer Seymour Sweeney and the DUP; Sweeney was a member of the DUP, although both he and the DUP denied that he had ever donated financially to the party.[16]

On 29 January 2008, Foster announced that she had decided against Sweeney's proposal for a £21 million visitors' centre on a protected greenfield site, reversing her earlier position of "being minded" to approve it.[17] Although the public funds for a causeway scheme remained frozen, it seemed highly likely that the publicly funded plan for the causeway would go ahead with the support of deputy DUP leader Nigel Dodds.[18]

A major concession for Northern Ireland was the reduction to zero of Air Passenger Duty on long-haul flights from the province. In the devolution settlement such burdens were to be born by the Assembly government. But negotiations proved how DUP could sell their support to Whitehall.[19] In 2011, she had written to the Organised Crime Task Force about the need to bring fuel licensing within the remit of the Petrol licensing Consolidation (NI) Act 1929, demonstrating the relevance of cross-border law enforcement jurisdiction in helping to reduce frauds.[20]

As the minister responsible for energy policy in June 2012, Foster criticised the Co-operative Group over the showing of a documentary opposing fracking, saying: "I find your claim that you take 'ethics to the next level' hard to reconcile with your demonstrable support for a film which presents a wholly one-sided and partial approach to the debate about hydraulic fracturing."[21]

In March 2014, Foster called for an apology for what she described as "deeply insulting" language" in a comment made by fellow MLA Anna Lo of the Alliance Party of Northern Ireland. Lo had described herself as "anti-colonial" and said the partition of Ireland was "artificial".[22] Foster herself was challenged in a blog by Irish writer Jude Collins over the fact that she had chosen to speak out so robustly on the matter after not commenting about remarks made the previous day by another Unionist politician, Progressive Unionist Party leader Billy Hutchinson. The former UVF member who was responsible for two sectarian murders during The Troubles stated that he had "no regrets in terms of my past because I believe that I contributed to preventing a united Ireland." Hutchinson also stated: "There is no room for violence in this society."[23][24]

On 11 January 2020 she was re-elected First Minister following the first meeting of the Assembly after restoration of devolution.

In December 2016, Foster faced criticism and controversy after a whistleblower revealed that the Renewable Heat Incentive scheme overspent by £400m, a failure which has been nicknamed the Cash for Ash scandal.[31] The scheme was originally set up by the Department of Enterprise, Trade and Investment (DETI, now Department for the Economy) when she was Minister of the department and the scheme offered incentives to businesses if they installed renewable heating systems, such as burning wooden pellets.

She faced strong criticism after it was claimed that she personally campaigned to keep the scheme open, even when senior civil servants warned of the overspend and the Minister responsible, Jonathan Bell, planned on closing it. It remained open for an extra two weeks before it was finally closed. It was also revealed that the Northern Ireland budget would lose £400m over the next 20 years as a result of the failure of the scheme. An independent audit investigated 300 sites and found there were issues at half of them, including 14 cases where there were suspicions of 'serious fraud'.

When senior civil servants suggested the closure of the scheme in September 2015, the Office of the First Minister and deputy First Minister (now the Executive Office) pressured the department to keep the scheme open, which is when there was a spike in applications.[32] There were calls for Foster to resign as First Minister after the scandal broke.[33][34]

On 9 January 2017, McGuinness resigned as deputy First Minister. Under the terms of the power-sharing agreement that created what is now the Executive Office, his resignation has also resulted in Foster being removed from office, until Sinn Féin nominates a new deputy First Minister; the party stated that it will not replace McGuinness. No nomination was made before 16 January, resulting in the collapse of the Executive. James Brokenshire, the Secretary of State for Northern Ireland, assumed the powers of the Executive and called for a snap election scheduled for 2 March.[35]

In a statement posted to Facebook, Foster said that she was "disappointed" with McGuinness' decision and condemned it as "not principled": "At a time when we are dealing with Brexit, needing to create more jobs and investing in our health and education system, Northern Ireland needs stability. But because of Sinn Féin's selfish reactions, we now have instability, and I very much regret that." She expressed concern over the possibility of another election less than a year after the previous one, and said "this is not an election of our making", but that "the DUP will always defend unionism and stand up for what is best for Northern Ireland."[36]

Since McGuinness' resignation, Northern Ireland has been in a continuous state of political deadlock as of September 2019.[37] One of the key issues is the Irish Language Act, which Sinn Féin insist on and Foster has said that her party will never agree to. With regard to the proposed act, she said "If you feed a crocodile, it will keep coming back for more." This remark was widely cited during the 2017 Northern Ireland Assembly election even though Foster later apologised for it.[38][39]
