British political advisor and activist
Nikki Da Costa is a British political advisor and activist. She was a special adviser serving as the director of legislative affairs in 10 Downing Street for two Prime Ministers: Theresa May from September 2017 until November 2018,[1] and again for Boris Johnson from July 2019 to August 2021.[2] She was heavily cited in the High Court case regarding the prorogation of parliament in 2019, having provided written advice[3] to the then Prime Minister Boris Johnson that the prorogation should take place.[4] She was named one of the 100 most influential women in the UK by The House in 2020.[5]
Between her stints in Number 10, da Costa worked in public affairs, through the Cicero Group, and her own consultancy company.[6] More recently, she has worked as a specialist partner with Flint Global lobbying firm.[7] She alongside Mercy Muroki was an unpaid "Policy Fellow" to the Minister for Women and Equalities, Kemi Badenoch for 2023–24.[8]
Da Costa has occasionally written op-eds and other articles reflecting on her time in government and giving advice. She wrote in The Times in January 2022 regarding Partygate that Number 10 had "failed as a collective" to follow the COVID-19 lockdown standards it had set.[9][10][11]
She was the Conservative candidate in North East Hertfordshire at the 2024 United Kingdom general election.[12][13] Her election bid was defeated by Labour's candidate Chris Hinchliff.[14]
