For this week's BBC Radio 4 Profile, Mary Ann Sieghart focuses on Yvette Cooper, recently announced as the new Shadow Foreign Secretary.
Yvette Cooper became an MP in 1997 and became politically close to Gordon Brown. She's held a number of Ministerial roles, introducing sometimes controversial legislation and facing controversy herself during the MPs' expenses investigation. She has juggled high profile jobs with bringing up three young children and she won this week's shadow cabinet elections - by a large margin.
So how did Yvette Cooper manage to become so popular so quickly? And with this latest promotion, where might her political future take her in Ed Miliband's new Labour Party?
