We're planning another baby, say gay fathers of twins

The gay couple who paid £200,000 for surrogate twins after authorities refused to let them adopt are trying for more children.

Barrie and Tony Drewitt-Barlow have told The Independent on Sunday that a new surrogate mother was implanted with four embryos on Thursday in the hope of further siblings for twins Saffron and Aspen, who will be three next month.

On 9 December 1999 Barrie and Tony became the first gay couple in Britain to father their own children using in vitro fertilisation.

In their first full interview in nearly three years, the couple said that if the new surrogate mother-to-be failed to conceive they would turn to Britain's new adoption laws enabling them – as a gay couple – legally to adopt jointly.

They welcomed last week's vote allowing the change in the law and castigated Iain Duncan Smith, accusing the Tory leader of homophobia for imposing a three-line whip on his MPs to vote against the Adoption Bill.

Barrie, 34, said: "We have naturally Conservative values but they have lost our vote because of the view they take on our lifestyle."
