A Birmingham MP won a major victory in his battle for a ban on replica firearms when Tony Blair announced the proposal would be included in Labour's election manifesto.
Steve McCabe (Lab Hall Green) has led calls for an end to the sale of replica guns.
Mr Blair revealed Labour would launch a consultation on new laws to prohibit the sale and carrying of replica firearms, if it won a third term in office.
The measure was included in Labour's manifesto on crime, published yesterday by the Labour leader and Home Secretary Charles Clarke in advance of the upcoming General Election.
Critics of the proposal have claimed it could lead to children being prosecuted for playing with water pistols.
But Labour is planning to exclude fake guns "which no reasonable person could mistake for a real gun".
The policy could still mean the most realistic toy guns are taken off the shelves.
Last year West Midlands Police investigated 1,138 firearms-related incidents, but many of these involved imitation guns rather than working weapons.
Mr McCabe said: "The fear and horror caused when someone is threatened with a weapon is the same regardless of whether it is real or not.
"I am delighted by the announcement. Unless there is an exceptional reason, nobody should be able to carry a replica weapon.
"It is quite reasonable to consult on it, but I hope it will be put into effect as soon as possible."
Labour's proposals also include outlawing imitation guns which can be easily converted into real weapons and raising the minimum age to buy a knife from 16 to 18.
There would be an extra 24,000 community support officers across the country, more drug treatment and testing services, and a "three strikes and you're out" policy banning binge drinkers from city centres.
Mr Blair said the extra officers would revive " neighbourhood policing" in every community.
But David Davis, the shadow Home Secretary, said: "Tony Blair promised to be tough on crime and the causes of crime but as a direct consequence of this Government's policies, violent, anti-social behaviour, drug and alcohol related crime have gone up."
