She has also worked for the Labour Party as Regional Director in Yorkshire and the Humber and the North East, and was Agent for the Sedgefield by-election in which Phil Wilson MP replaced Tony Blair after his resignation from parliament. Twycross was placed third on Labour’s Assembly list for the 2012 London Assembly election and was elected as a Londonwide Assembly Member in May 2012.

Twycross was a member of the London Fire and Emergency Planning Authority from 2012 until its abolition in 2018.

Campaigns and activities
Twycross has led a number of campaigns since being elected to the Assembly, notably leading a London Assembly investigation into the rise in food poverty in London which called for London to be a Zero Hunger City. Boris Johnson subsequently adopted the goal as part of his 2020 vision making London one of just two cities worldwide to sign up to the UN’s Zero Hunger Challenge. Twycross has led the Labour 999SOS campaign, fighting cuts to emergency services since its launch in October 2012. In her former role as the London Assembly Labour Group's Economy spokesperson, Twycross challenged former Mayor of London Boris Johnson over low pay and poverty in London and over the use of zero hours contracts at City Hall. In September 2013, Twycross co-founded the Labour Campaign for Universal Free School Meals with the GMB Union and Richard Watts, Leader of Islington Council. In November 2018, London joined the 100 Resilient Cities project and Twycross was appointed to the role of City Hall's Chief Resilience Officer by Sadiq Khan.
