Lucy Allan, MP for Telford, will vote in favour of the Assisted Dying Bill when it is debated in Parliament on 11 September.
The bill gives terminally ill patients the right to end their lives in specific and controlled circumstances.
Lucy Allan MP said: "The time is right for Parliament to debate this issue. There is a clear need for legal clarity. This bill gives the terminally ill choice in the manner of their death, it gives them a say in when prolonged suffering goes beyond what is endurable. It offers the terminally ill the option of dying in peace.
"There are many who misunderstand this bill and argue that it would be the first step on the path to legalising euthanasia. This bill only relates to those suffering a terminal illness. The bill does not apply to those who are disabled, elderly, depressed or suffering from dementia. This bill does not legalise euthanasia.
"For me it is about personal freedom, about giving the individual the right to choose what is best for them and their family at the end of life. It cannot be right that the State can force someone dying a painful death, to have that process of dying prolonged against their wishes. Our lives belong to us not to the State.
"We all have an innate need maintain some control, autonomy and dignity, as much at the end of life, as we do during life. It is not for the State to take that from us.
"I hope that as many MPs as possible attend this important debate and vote on this issue."
