Fiaz was elected as mayor of Newham in May 2018. Since her election, she has been leading a transformative and radical agenda in the London borough, reflecting a series of manifesto commitments to address inequality and poverty, invest in young people to widen opportunities, embed community wealth building as the economic approach being adopted by the council, increase participatory democracy and respond to the climate emergency. As part of an ambitious programme of scaling up council housing delivery in the borough, she is leading one of the most ambitious genuinely affordable housing programmes in London through a number of significant regeneration schemes. Under her leadership, Newham also became the first council in the country to make the health, happiness and wellbeing of its residents the key indicator of economic success. As an advocate for racial justice and equality, Fiaz was awarded an OBE in 2019 for services to Black and minority ethnic communities in the UK.
