Iranian delegate demanded holding discussions on these proposals and postponing the voting for 24 hours in accordance with the OPCW rules of procedure.
Iran’s Permanent Representative to the conference of the Chemical Weapons Convention (OPCW) said,"Iran is against consensus voting Britain’s proposals must be discussed first".
The Organisation for the Prohibition of Chemical Weapons (OPCW) voted on Wednesday to support a British-led motion for the body to have the power to attribute responsibility for attacks using banned weapons in Syria.
Foreign Secretary Boris Johnson had been at the OPCW's headquarters in The Hague to push for the proposal on Tuesday.
Welcoming the decision, Johnson said: "Chemical weapons are an affront to human dignity and have no place in the 21st century.
"The international community has quite rightly come together today to strengthen the ban on chemical weapons and prevent impunity for their use.
"The UK has led the diplomatic efforts to secure this action.
"We look forward to working with all countries who are members of the Chemical Weapons Convention to implement the decisions taken today, and we will continue to push back on any efforts to undermine the ban on these vile weapons."
The UK's permanent representative to the OPCW, Peter Wilson, revealed 82 states voted in favour of the UK-led motion, while 24 opposed the move.
A two-thirds majority was needed for it to pass.
Mr Wilson, who is also the UK's ambassador to the Netherlands, tweeted there was an "overwhelming majority to restore the taboo" against chemical weapons.
Russia,Iran and Syria were the countries to vote against.
After the result, its industry minister Georgy Kalamonov compared the OPCW to a sinking ship.
"A lot of the countries that voted against the measure are starting to think about how the organisation will exist and function in the future," he said.
The current conference of the Chemical Weapons Convention participants was convened by Britain, which is keen to empower to OPCW to name those responsible for the use of chemical weapons.
Currently the OPCW has the right to provide experts’ technical conclusions.
In fact tries to hand over to the OPCW, which is under a strong influence of the Western countries, some functions of the UN Security Council, which enjoys the right to attribute responsibility for chemical weapons attacks.
