Sefton Central Labour MP Bill Esterson says Prime Minster David Cameron's plans to 'end council housing for life' will result in families in Formby, Crosby, Maghull and Aintree Village being made homeless.
The Conservative-Lib Dem coalition government has announced proposals to restrict social housing tenancy.
Under the plans, tenants would be granted housing for no more than a five year period.
But Bill Esterson said the plans were another attack on the poorest in society and would see families being kicked out of their homes right here in Sefton.
Bill said: "David Cameron and the Conservative-Lib Dem government really are showing their utter contempt for ordinary people and families who aren't born with the privileges they have been lucky to be born with.
"This government is so out of touch with what life is really like. They are decimating the public sector through ill-thought out cuts which in turn will drive up unemployment. Social housing is more important now than ever as people will need help following the after affects of this government's economic policy.
"Sefton Central will be worst hit by this as we have a very large portion of people who work for the public sector and who face redundancy at the hand of this government's cuts."
Bill said the result of the Prime Minister's plans will be disastrous for family life.
He said: "It really is outrageous. The Conservative and Lib Dems really aren't taking into account what their policies will do to ordinary families.
"How can parents ensure there is a stable family life for their children when they will be moved on within five years?
"How can parents plan ahead for schools for their children if the family don't know where they are going to be living?
"The coalition government clearly hasn't thought this through or what the consequences for their ill-conceived schemes will be for ordinary people.
"I will fight this heartless plan every single step of the way."
