Labour leader Jeremy Corbyn has unveiled his shadow cabinet, including those responsible for energy and the environment.
Lisa Nandy is shadow secretary of state for energy and climate change, while Kerry McCarthy becomes shadow secretary for the environment, food and rural affairs.
Nandy, MP for Wigan, replaces Caroline Flint. Nandy's previous posts include shadow Cabinet Office minister and shadow minister for education.
Meanwhile, Bristol East MP McCarthy replaces Maria Eagle, who becomes shadow defence secretary. McCarthy has held several posts in Labour's shadow cabinet, including shadow minister for foreign and commonwealth affairs and shadow Treasury minister.
Last week, McCarthy proposed a bill on food waste reduction, which would require supermarkets, manufacturers and distributors to reduce food waste by 30% by 2025, and donate to charities their unsold food.
The bill was given leave to proceed and its second reading has been scheduled for 29 January 2016.
Jon Trickett, MP for Hemsworth, will take over as shadow secretary of state for communities, while Lilian Greenwood, MP for Nottingham South, will be shadow transport secretary.
Corbyn said: "We have delivered a unifying, dynamic, inclusive new shadow cabinet, which for the first time ever has a majority of women.
"The shadow cabinet is a strong combination of change and continuity that will now come together to hold this government to account."
