Gay nuptials will begin just after midnight Friday in Britain as a gay marriage law approved by lawmakers last year takes effect.

Multiple venues across Britain and Wales are jockeying to hold the first ceremonies.

At London's Camden Town Hall, Sean Adl-Tabatabai, 32, and Sinclair Treadway, 20, will be married in front of 100 guests. A late-night reception will feature drinking and dancing.

“Some people say, 'You gays are trying to redefine marriage,' but the definition of marriage has already changed,” Treadway, a student originally from Los Angeles, told the AP. “Now it's between two people who love each other.”

CNN profiled another couple preparing to make history.

Andrew Wale and Neil Allard will be the first gay couple to marry in Brighton. The couple will exchange vows in the music room of the Royal Pavilion.

Together 7 years, the couple won an essay contest to be the city's first gay couple to marry.

“When we were born it was illegal to be gay, let alone get married,” Wale told CNN.

BBC reported that the Brighton Gay Men's chorus will sing at the wedding of James Preston and Phil Robathan, the first gay couple to marry at Brighton Town Hall.

Polls show about two-thirds of Britons support allowing gay couples to marry.

Prime Minister David Cameron backed the marriage law, roughly three decades after Prime Minister Margaret Thatcher's government approved legislation banning schools and local authorities from “promoting homosexuality.” Both have led Britain's majority Conservative Party.
