A woman priest and her partner are aiming to become Britain's first legally married lesbian couple. The Rev Debbie Gaston and Elaine Cook are among three couples set to have same sex weddings in Brighton on December 21. They will marry a second after midnight on the first day the Civil Partnership Bill legalises same sex weddings. The Rev Gaston, 46, of the Metropolitan Community Church, and Elaine, 53, have been together for 16 years and they have two children. She said: "As a vicar I obviously believe whole-heartedly in the concept of marriage and I have married more than 30 couples myself. "Elaine and I have waited many years to be able to make this kind of commitment to each other and we both see the Civil Partnership Bill as a huge step in the right direction for equality. "However, we are only part way there. Until I can have a legal ceremony in the eyes of God I will not feel completely fulfilled." They will marry in a joint ceremony with two other gay couples - Gino Meriano and his partner Mike Ullett; and Roger Lewis, a Sussex Police employee and partner Keith Willmott-Goodall.
