In the wake of the British Conservative Party's endorsement of gay marriage, President Barack Obama is being urged to follow in the footsteps of Prime Minister David Cameron and endorse such unions.

On Saturday, Equalities Minister Lynne Featherstone unveiled plans to make gay marriage legal in Britain before 2015.

Cameron's Conservative Party governs in coalition with the Liberal Democrats, whose members are in favor of full marriage for gay and lesbian couples.

At the Liberal Democrats party conference, Featherstone said denying gay couples the right to marry is “not fair.”

“Britain must not get complacent,” she said. “We are a world leader for gay rights, but there is still more that we must do.”

Gay marriage proponents in the United States cheered the news, and urged Obama to follow.

“Today's terrific news out of Britain reinforces what we have seen in state after state – anything short of marriage, by any name, simply does not convey the full meaning, understanding and protection that marriage brings,” said Marc Solomon, national campaign director of Freedom to Marry.

“It's particularly impressive that Prime Minister David Cameron, the leader of the British Conservative Party, is leading the charge to move to full marriage in the UK. We repeat our call on President Obama to join Cameron in offering principled leadership, finish his 'evolution,' and join the majority of Americans who support the freedom to marry.”
