Frances O'Grady is to step down as General Secretary of the Trade Union Congress later this year after ten years.
Highly respected across the labour movement, the 62-year-old was the first woman to be elected to the trade union body's top job in 2013.
She drew widespread praise for helping to negotiate the furlough scheme, which protected workers during the Covid pandemic, and began her career with the Transport and General Workers' Union, campaigning for a national minimum wage.
