Colombia's historic peace accord with the FARC guerrilla group is likely to be approved in a national referendum, according to three opinion polls published Tuesday.
Polls conducted on behalf of Colombia's major news outlets all agreed that a majority of voters in Sunday's plebiscite would vote yes on the deal, which must be approved by popular vote to take effect.
A poll published by Semana magazine and broadcaster RCN showed 66 per cent of likely voters supporting the deal. A separate poll by Radio Caracol and the Red + news network showed a 62 per cent majority for yes votes. A third poll conducted on behalf of daily El Tiempo and W Radio showed 55 per cent planning to vote in favour.
Colombian President Juan Manuel Santos and Revolutionary Armed Forces of Colombia Commander Rodrigo Londono signed the peace accord in a ceremony before more then 2,000 people in Cartagena Monday evening.
The centre-right government is joined by a broad coalition of supporters from across the political spectrum in urging a yes vote on the deal, which ends 52 years of armed conflict that left more than 220,000 people dead and displaced millions.
Former president Alvaro Uribe and his far-right Democratic Centre party oppose the deal, arguing that it concedes too much to the Marxist FARC.
If the accord is approved in Sunday's vote, FARC's roughly 8,000 armed fighters will turn over their weapons to United Nations inspectors in a six-month disarmament process and begin the process of rejoining society.
A no vote would effectively scrap the deal.
