Jean began her career as a teacher of modern languages at a secondary school in Chingford, east London. She continued to teach for more than two decades, until leaving the profession in 1999 to concentrate on her Euro election campaign. Her career as a teacher stood her in good stead for managing outspoken politicians in the European Parliament. Jean lives in the borough of Waltham Forest, east London.

She proceeded to hold a number of positions including Co-Chair of the Party Council, Chair of the Party Executive, Representatives to the Federation of European Green Parties and Political Liaison to the Green Group in the European Parliament, before being elected as the Green Party’s MEP for London in 1999. She was re-elected with an increasing share of the vote year on year in 2004 and 2009.
