Davao, Philippines - Philippine president-elect Rodrigo Duterte is planning to visit the Vatican to make a personal apology to the pope for calling him a "son of a w****", the politician's spokesman said on Thursday.
"The mayor repeatedly said he wants to visit the Vatican, win or lose, not only to pay homage to the pope but he really needs to explain to the pope and ask for forgiveness," Peter Lavina told reporters in the southern city of Davao.
Duterte, 71, the longtime mayor of Davao, surged to a landslide election win on Monday following an incendiary campaign in which he gleefully used foul language to disrespect authority figures.
In a rambling speech to announce his presidential run, Duterte lashed out at Pope Francis for causing traffic jams in Manila when he visited the mainly Catholic nation last year.
"It took us five hours to get from the hotel to the airport. I asked who was coming. They said it was the pope. I wanted to call him: 'Pope, son of a w****, go home. Don't visit anymore'," said Duterte.
Catholic leaders in the Philippines condemned Duterte's comments but, like many other controversial remarks, they had little impact on his popularity.
Other campaign firebombs included saying he wanted to rape a "beautiful" Australian missionary who was sexually assaulted and murdered in a 1989 prison riot in Davao.
He used "son of a w****" to describe many opponents and critics, including current President Benigno Aquino.
Duterte also vowed repeatedly that he would kill tens of thousands of suspected criminals in an unprecedented law-and-order crackdown, and boasted so many bodies would be dumped in Manila Bay that the fish would grow fat from feeding on them.
Duterte had already apologised to the pope in a letter and received a response from the Vatican offering "the assurance of prayers", his aides said on the campaign trail.
Duterte said publicly the pope was the victim of a "stray bullet" resulting from his gutter language and frustration with government incompetence.
Lavina said Thursday no schedule had yet been set for the Vatican trip, although it was a top priority.
Duterte is due to be sworn into office on June 30 for a term of six years.
Despite being raised as a Catholic, Duterte openly said he fathered four children by four women.
Among his closest friends and advisers is Apollo Quiboloy, leader of the Davao-based Kingdom of Jesus Christ religious group who openly calls himself "the Appointed Son of God".
Lavina has said repeatedly in recent days that Duterte plans to adopt a more moderate and presidential tone when he assumes office, and that his gutter language and insults were part of a performance to attract voters' attention.
"You have to understand the Philippine style of elections. The context is most of our politicians need to communicate to our audience so many of our politicians sing and dance," Lavina said on Wednesday.
"Some make jokes, some make funny faces. Some dress outrageously. So it is all in this context that all these jokes, bantering, happen during the campaign. We don't expect the same attitude of our officials thereafter."
Lavina was explaining a joke Duterte made about burning Singapore's flag, which provoked an angry response from the city-state's embassy.
Duterte also stirred diplomatic anger when he warned that he was prepared to sever ties with the United States and Australia, two of the Philippines' longest and most important allies.
He was reacting to criticism from the US and Australian ambassadors over his rape comments, and told them to "shut their mouths".
Duterte made his controversial rape comments as he recounted at a campaign rally the 1989 riot, in which he said he personally shot dead some of the inmate instigators.
But then he said in the aftermath of the riot that he discovered that an Australian missionary had been raped and murdered.
"I was mad she was raped. But she was so beautiful. I thought: 'The mayor should have been first'," said Duterte, who on the campaign trail also repeatedly boasted about his mistresses and sexual prowess.
