Yvette has voted to support same-sex marriages in a historic vote in Parliament this week.
Under the plans, same-sex couples who love each other and want to get married would be able to marry in a civil ceremony with a registrar.
Religious organisations such as the Quakers, who want to celebrate same sex marriages would also be able to do so.
Religious groups that don’t support same-sex marriages will not have to. And there are a series of "locks" to stop any minister or church being required to hold same-sex marriages if they don't want to.
Yvette Cooper MP said:
“If couples who really love each other want to make a long term commitment and get married, Parliament shouldn't stop them just because of their gender or sexuality. I’ve had letters from people on both sides of the debate and I respect the deeply held feelings of people on both sides, but I believe that when people love each other we should welcome and celebrate it.
"Some people opposed civil partnerships when they were introduced, but they have strong support now. It is welcome that most people also already support the chance for gay and lesbian couples to get married too.
"Freedom of religion is really important, and no church will be required to hold same sex marriage if they don't want to. But those who do want to should have the choice."
