The bill will make reproductive cloning illegal again
The bill, which should pass all stages in the Commons on 29 November, makes it a criminal offence "to place in the womb of a woman a human embryo that has been created other than by fertilisation".
Critics say the government is rushing to bring forward bad legislation and they will make strenuous efforts to amend it.
Medical malpractice
The government action was deemed necessary after anti-abortion campaigners, the Pro-Life Alliance, won a High Court ruling last week that laid bare a major deficiency in the legislation covering embryology research.
This flaw centred on the legal definition of an embryo - the union of an egg and a sperm.
Because a clone is produced in a different way, the judge ruled that current regulations did not embrace the new technology.
This loophole, in theory, could allow someone to conduct cloning experiments without the licensed permission of the Human Fertilization and Embryology Authority, the body that is supposed to oversee this area of research.
In reality, commentators said, other laws relating to medical malpractice and even assault could be used to prevent cloning experiments.
Therapeutic cloning
Nevertheless, the government is determined to remove the legal flaw. It also intends to appeal against the High Court ruling.
The government's critics say the country's embryology legislation is deeply flawed and there is little point in merely trying to patch it up.
Peers and MPs opposed to the use of embryos for research on ethical grounds say they will attempt to amend the bill so that both reproductive and therapeutic cloning are banned.
'Proven success'
Richard Gardiner, chairman of the Royal Society, argues this would be wrong: "We need to secure a watertight ban on reproductive cloning," he told BBC Radio 4's Today programme.
"But we would argue very strongly not at the expense of therapeutic cloning, which is a vital technique for helping us to understand how you can reprogram the genetic information from specialised cells so that we can more effectively help patients."
Lord Alton, who opposes all forms of human cloning, told Today an alternative had emerged since previous legislation was drafted.
"Since January last, impressive new evidence... illustrates that there is an alternative, and that's the use of adult stem cells.
"There's a vast biomedical potential there, a proven success record in laboratory culture and a proven success record in current clinical treatment," he said.
Lib Dem protests
Liberal Democrat MPs were protesting on Thursday night that there was insufficient time for proper debate.
Andrew Stunell, Lib Dem MP for Hazel Grove, asked Leader of the House Robin Cook if he was "satisfied" that "the amount of time is sufficient for a properly measured debate and that the framework of the bill is sufficient to allow sensible amendments to be added to it?"
Mr Cook replied: "What we are seeking to do is no more than what was understood to be the state of the law before the ruling last week.
"It may well be that at a future time we need to look at further measures in examining this issue but for the time being we do need emergency measures to prevent those coming to Britain in order to exploit the loophole that has been shown by the court decision."
