All of Waltham Forest's MPs voted in favour of gay marriage in last night's historic Commons vote.
Chingford and Woodford Green Tory cabinet member Iain Duncan Smith, Leyton and Wanstead Labour MP John Cryer and Walthamstow Labour MP Stella Creasy all backed the proposals.
Overall, MPs voted by 400 to 175 to make same-sex marriages legal, although a majority of Conservatives voted against the bill put forward by their own party.
Campaigners have hailed the vote as an important step forward for gay rights, but some critics say marriage should only be between a man and woman, while others said the bill was flawed.
The bill was agreed in principle and will now undergo further Parliamentary scrutiny and possible adjustments before becoming law.
