Alistair Luke Strathern (born 5 March 1990) is a British Labour Party politician who has served as the Member of Parliament (MP) for Hitchin since 2024.

[11] He was a Labour councillor for the ward of Higham Hill on Waltham Forest London Borough Council from 26 May 2014 until his resignation on 5 September 2023.

[21] Also in January 2024, he announced his intention to contest Hitchin at the 2024 general election, which would include his home in Shefford and other parts of Mid Bedfordshire due to boundary changes.

[6] His involvement in the protest was revealed some months later, and sparked calls by the defence secretary Grant Shapps for his parliamentary candidacy to be withdrawn.

[26][27] A photograph of Strathern at the protest dressed as a zombie appeared on the front page of The Sun on 8 August 2023, under the headline "Wannabe Labour MP unmasked as 'zombie' Greenpeace zealot".
