John Robert Biggs (born 19 November 1957) is a British Labour Co-op politician who was Mayor of Tower Hamlets between 2015 and 2022.

He led Labour to a landslide victory in 1994, leading the campaign to remove the UK's first BNP councillor, and the populist but discredited Liberal Democrat administration.

[2] After standing down as leader in 1995, he remained an active councillor but also attended Law School, served as Director of the Socialist Health Association (1997–2000), and was Deputy Chair of Bow Housing Action Trust (1995–2004).

[7]Having won selection as the Labour candidate for directly elected Mayor of Tower Hamlets, Biggs stood against incumbent Lutfur Rahman in 2014.

Livingstone reversed his public position after auditors were appointed to investigate allegations of mismanagement and fraud at the council, but remained privately supportive.

Rahman and his allies robbed the people of Tower Hamlets of the free and fair mayoral election they deserved and betrayed everyone in our community who trusted and voted for him, by setting out to break the rules and going to extraordinary lengths to win.

[13]In 2014 Rahman's actions while in office led to government appointed commissioners being brought in to the council to review its grant making practices.

His first term in office was dominated by addressing the concerns caused by Rahman's actions, and successfully having the government directions lifted.

Biggs won the election with 44,865 (72.66%) votes to Kahn's 16,878 (27.34%), and his leadership resulted in Labour increasing its number of councillors to 42 out of 45.

[26] Like other London Council Leaders, this all took place to a backdrop of massive budget savings, while working to protect services from national funding cuts.

As a result of work achieved during Biggs tenure Tower Hamlets London Borough Council won a number of awards and was shortlisted for a number of others,[27] including Biggs lost re-election in 2022 to Rahman and his newly formed Aspire Party by 40,804 (54.90%) to 33,487 (45.10%) votes, a result viewed by many as a surprise.
