BOGOTA/BUCARAMANGA, June 19 (Reuters) - Leftist Gustavo Petro, a former member of the M-19 guerrilla movement, who has vowed profound social and economic change, won Colombia's presidency on Sunday, the first progressive to do so in the country's history.
Petro beat construction magnate Rodolfo Hernandez with an unexpectedly wide margin of more than 700,000 votes in what analysts said was a demonstration of Colombians' eagerness for efforts to combat deep inequality.
Petro, a former mayor of capital Bogota and current senator, has pledged to fight inequality with free university education, pension reforms and high taxes on unproductive land. He won 50.5% to Hernandez's 47.3%.
Petro's proposals - especially a ban on new oil projects - have startled some investors, though he has promised to respect current contracts. read more
His victory was likely to cause market jitters until his cabinet is announced, analysts told Reuters on Sunday.
"From today Colombia changes; Colombia is different," Petro told cheering supporters in Bogota's concert arena. "Change consists precisely in leaving behind sectarianism."
"It is not a time for hate, this government, which will begin on Aug. 7, is a government of life," he said.
Alejandro Forero, 40, who uses a wheelchair, cried as results came in.
"Finally, thank God. I know he will be a good president and he will help those of us who are least privileged. This is going to change for the better," said Forero, who is unemployed.
Thousands of people took to the streets in Bogota to celebrate, with some dancing near its largest polling place under intermittent rain.
This campaign was Petro's third presidential bid and his victory adds the Andean nation to a list of Latin American countries that have elected progressives in recent years.
Petro's victory showed people in Colombia - where nearly half the population lives in some form of poverty - are eager to fight inequality, said Daniela Cuellar of FTI Consulting.
"What the Colombian population demonstrated today is that they are seeking a government focused on key social issues," she said. "Colombia's longstanding ailments of inequality, which were exacerbated by COVID-19, have contributed to the electorate seeking a shift."
But a fragmented congress, where a dozen parties have seats, will act as a check on Petro's proposals.
"Colombia's institutional strength and rule of law appear sufficiently robust for the country to maintain economic stability," Cuellar said. "Moreover, campaigning is not governing, Petro's policies will be more moderate."
"Even if he tries to pass radical reforms, he does not have the congressional support to implement them," she added.
Petro, 62, said he was tortured by the military when he was detained for his involvement with the guerrillas, and his potential victory had high-ranking armed forces officials bracing for change. read more

"Today I'm voting for my daughter - she turned 15 two weeks ago and asked for just one gift: that I vote for Petro," said security guard Pedro Vargas, 48, in Bogota's southwest on Sunday morning.
"I hope this man fulfills the hopes of my daughter, she has a lot of faith in his promises," added Vargas, who said he typically does not vote.
Petro has also pledged to fully implement a 2016 peace deal with FARC rebels and seek talks with the still-active ELN guerrillas.
Analysts have said the proposed halt to oil development could send investment elsewhere at a time when Colombia is struggling with low credit ratings, a large trade deficit and national debt which has doubled to 72% of GDP over the last decade.
Oil accounts for nearly half of exports and close to 10% of national income, but Petro argues new projects should be barred for environmental reasons and to move Colombia away from dependence on the industry.
Petro has also promised to increase taxes and royalties on extractive industries and charge major landholders for unproductive land, raising some $5.2 billion. He also proposes to raise up to $3.9 billion by progressively taxing companies.
"We think on Tuesday both interest rates on TES bonds and the exchange rate will depreciate, but we need to see what type of rhetoric Petro gives us, what type of cabinet he'll give us," said Sergio Olarte, head economist for Colombia at Scotiabank.
Monday is a holiday in Colombia.
"The magnitude of movements in the coming trading sessions will depend on the economic line that the new president offers," agreed David Cubides, head economist at Allianz brokerage, who said he expects local market volatility during the next week.
Current President Ivan Duque tweeted he had called to congratulate Petro, and they have scheduled a meeting in coming days to ensure a harmonious transition.
Colombian presidents are limited to one term.
Some 22.6 million people voted, about 1.2 million more than in the first round. Some 2.3% of voters turned in protest votes, backing neither candidate.
