Caroline Lucas, the environmental party’s leader and a member of the European Parliament for South East England, won the Brighton Pavilion seat, overturning a Labour majority of 5,000 in the process.
“Tonight the people of Brighton Pavilion have made history by electing Britain's first Green MP,” a jubilant Lucas said. “Thank you so much for putting the politics of hope above the politics of fear.”
The Greens have already found a foothold in Brighton. It already had a number of councillors on the local authority.
With more than three-quarters of the national results announced, the Greens had taken just under one percent of the vote, about the same as at the last election in 2005.
