Justine Greening was born in Rotherham, the daughter of a steel worker and first in her family to go to university. Campaigning for the Conservatives, she won back a Tory stronghold from Labour in the 2005 general election becoming MP for Putney. She began politics in opposition, but became a Cabinet Secretary in David Cameron’s government, and remained there for Theresa May’s premiership as Education Secretary. Now having left Parliament, Justine is never far from politics – she founded the Social Mobility Pledge and now even runs her own podcast.
