The public is divided over whether to allow transplants of organs from brain-dead people who have not made it clear whether they wish to become donors, according to a government survey.

The Cabinet Office study, released Saturday, found that 35.4 percent of respondents believe such transplants should be forbidden because the intent of brain-dead people cannot be confirmed, while 45.5 percent say it should be up to a brain-dead person's family to decide.

Only 9.7 percent said transplants should be allowed as long as the brain-dead people have not explicitly refused to donate their organs.
