Laird was born in Greenock and educated at James Watt College, Caledonian University and then Edinburgh Napier University. Prior to election, she was employed in senior human resources posts in the electronic, semiconductor and financial service industries. Laird was first selected by her Constituency Labour Party to contend the 2012 local elections, and was returned alongside her Scottish Labour running mate. She was appointed spokesperson for economy and planning in February 2013 and one year later was elected by her fellow Labour councillors to the post of deputy leader. Laird spoke on behalf of Fife Council at the Barclay Review looking at non-domestic rates across Scotland and called for reform, saying the current scheme favoured out-of-town retailers. She led the call from Fife Council for a radical overhaul of the Scottish planning system. She also secured regeneration of Fraser Avenue in Inverkeithing, a project which was commended by the Saltire Society. Laird sought selection for the Scottish Labour regional list for the Mid Scotland and Fife region in the 2016 Scottish Parliament election.
Parliamentary career
For the 2017 snap general election, Laird was selected to stand as the Scottish Labour candidate for the Kirkcaldy and Cowdenbeath constituency; once held by former Prime Minister Gordon Brown. She overturned Roger Mullin of the SNP's majority to become the constituency's new Member of Parliament, receiving 36.8% of the vote. Laird was appointed Shadow Secretary of State for Scotland less than a week later on 14 June 2017. Laird's maiden speech at the House of Commons focused on poverty in her constituency and quoted Kirkcaldy-born economist Adam Smith, as well as former PM Winston Churchill: Laird continued to regularly campaign on poverty issues in the constituency, working in partnership with local charities in a bid to overturn the UK government’s new flagship welfare policy, Universal Credit. By enlisting support from Women Against State Pension Inequality campaigners, Unison and Citizens Advice Rights Fife, Laird also hosted a number of public campaign events aimed at 1950s-born women who were affected by age-related eligibility changes. In response to public concern with ongoing flaring at Fife Ethylene Plant, Laird established a Mossmorran Working Group, the first to include cross-party elected representatives, community groups, as well as representatives from FEP operators Shell UK, ExxonMobil, the Health and Safety Executive and the Scottish Environment Protection Agency also attended. Laird held a public meeting with ScotRail director Alex Hynes in Kirkcaldy in February 2019, to discuss franchise operator Abellio's poor performance record in Fife, particularly during that winter, when stop-skipping and train delays were a regular occurrence. Although transport issues were devolved, Laird later lobbied the Scottish Government to use an early break-clause in its Abellio contract. On 18 December 2019, transport minister Michael Matheson announced he would cancel the contract three years early, in 2022. Laird intervened when local constituents fell victim to automated push payment fraud. Despite the Santander Bank's insistence that they were not at fault, Laird later succeeded in securing a £278,000 repayment to victims. She also campaigned against bank closures across the constituency. The MP secured a pledge from the Ministry of Defence to finance work to clean-up radiation at Dalgety Bay - an issue blighted by two decades of inactivity. Laird called for reform to planning law after residents objected to large-scale development in Aberdour, and campaigned for regeneration of Kirkcaldy town centre, holding talks with Columbia Threadneedle, former owners of the Postings, and LaSalle, former owners of the Mercat. She argued for government intervention for local industry to protect jobs, most notably in the case of Bifab and Babcock at Rosyth shipyard. In May 2018, Laird faced criticism for neglecting her duties as a councillor, having only attended two meetings after her election as an MP. Critics argued she should have resigned as a councillor when becoming a Member of Parliament. Her party's rules later stated members should only hold one elected position, a policy Laird appeared to have breached, according to the National newspaper. However, Laird actually resigned the post of her own volition. Laird resigned as deputy leader of the Scottish Labour in December 2019 after losing her seat to the Independent candidateNeale Hanvey. Following her resignation, she criticised unsupportive members of her party for undermining the leaderships of Jeremy Corbyn and Richard Leonard. Laird endorsed Keir Starmer in the 2020 Labour Party leadership election.
