Jubilant gay rights campaigners were last night celebrating the succesful passage of the Marriage (Same Sex Couples) Bill through the House of Lords - and vowing to take the fight for marriage equality to Scotland and Northern Ireland.
MPs will this evening debate amendments made to the legislation in the Upper House, but this is expected to be little more than a formality and is unlikely to delay its progress into law, with Royal Assent within the next few days.
The Labour Party has published a video message from leader Ed Miliband in support of the London Pride parade.
"It promised to be a very, very important year if we can get the same-sex marriage bill passed," said Miliband.
"I'm proud to support that bill because I believe that the gender of the person you love shouldn't determine whether you can marry them."
Gay rights campaigners in America are celebrating a double landmark victory after the Supreme Court ruled that same sex married couples should be granted the same rights and benefits as heterosexual couples.

Google has created a rainbow border for its search box for users who type the word 'gay' or 'lesbian' into their search engine.
A crowd of thousands gathered in Washington to celebrate the Supreme Court striking down a part of a federal law denying federal benefits to married gay couples.
The court's 5-4 vote said the Defence of Marriage Act, known as Doma, denied equal protection to same-sex couples.
The ruling means that previous anti-gay marriage laws denying legally married same-sex couples from receiving tax, health and pension benefits has been swept away.
The court also upheld a trial court declaration that ruled that California's Proposition 8 was unconstitutional, paving the way for same-sex marriages to continue in the state.
Proposition 8 was approved in 2008 with 52% of the vote and put same-sex marriages on hold.
The verdict read:
"Under Doma, same-sex married couples have their lives burdened, by reason of government decree, in visible and public ways.
"Doma's principal effect is to identify a subset of state-sanctioned marriages and make them unequal."
President Obama has welcomed a US Supreme Court decision to make married gay men and women eligible for federal benefits, whilst stressing the ruling does not change the way religious institutions define marriage. In a written statement, he said:
We are a people who declared that we are all created equal, and the love we commit to one another must be equal as well.
The US president said the ruling applies only to civil marriages and that how religious institutions define and consecrate marriages has always been up to those institutions.
The US Supreme Court has extended Federal benefits to married gay couples.
Gay marriage campaigners have welcomed the House of Lords' decision to reject a bid aiming to block the legislation.

This is a victory for love, marriage and equality.
We are another step closer to our goal of equal marriage. It signals that the House of Lords accepts the principle that we should all be equal before the law.
– Ben Summerskill, Stonewall chief executive
In the last 24 hours alone, opponents of equality in the House of Lords have compared loving, committed relationships to incest and polygamy.
Britain's 3.7 million gay people don't deserve to be second class citizens in their own country. A tough fight lies ahead and we'll continue to work tirelessly every single day to get equal marriage through the Lords.
