Ministers said lawmakers needed to focus on important revisions
to rules governing stem cell research and other scientific advances, ra-
ther than examine the emotive issue of abortion – which isn't covered
by the draft laws.
Brown is a strong advocate of stem cell science and has said Brit-
ain owes it to future generations to support the research. Opponents
warn an easing of laws on creating embryos could lead to the genetic
engineering of human beings.
The process involves injecting an empty cow or rabbit egg with
human DNA. A burst of electricity is then used to trick the egg into
dividing regularly, so that it becomes a very early embryo, from which
stem cells can hopefully be extracted.
Scientists say the embryos would not be allowed to develop for
more than 14 days.
Under the new laws, in-vitro fertilization clinics will no longer
have to consider the need for a child to have a father when deciding
whether to offer treatment to lesbian couples.
Opposition Liberal Democrat lawmaker Evan Harris said he had
hoped the debate would allow him to put forward proposals to extend
the right to have an abortion to women in Northern Ireland – where
terminations are not permitted.
Nadine Dorries, a lawmaker with the main opposition Conserva-
tives who attempted in May to reduce the upper time limit for abor-
tions in Britain, said the government had ducked a potential fight over
terminations.
British lawmakers voted in May in favor of keeping the current
upper time limit for abortions of 24 weeks.
