Love conquers all, even political differences.

The marriage this week of the grandchildren of former president Ferdinand Marcos and former senator Raul Manglapus signals the end of a decades-long rivalry, Ilocos Norte Gov. Imee Marcos said Saturday.

"Many years ago my father was . . . gravely disappointed and saddened by the (loss) to the Supreme Court in his right to travel back home. That is the Supreme Court case Marcos vs. Manglapus," Marcos said during a thanksgiving celebration of the wedding of her son, lawyer Ferdinand Michael Manotoc, to Carina Amelia Manglapus.

"Tonight we have reversed that miserable ruling . . . Cara joining our family, love wins."

Manotoc and Manglapus' wedding on Wednesday was held privately in Makati.

On Saturday, Laoag Bishop Renato Mayugba presided over a thanksgiving mass held at Paoay church. Environment Secretary Roy Cimatu, presidential adviser Francis Tolentino, and presidential spokesman Harry Roque were in attendance.

Ilocos Norte Rep. Imelda Marcos said: "I'm very, very happy today because two families that are in contrast for so many years suddenly fell in love."

Ferdinand Marcos won the 1965 presidential election over Raul Manglapus, who later became one of the pro-democracy opposition leaders based in the US.

Manglapus served as the foreign affairs secretary of former President Cory Aquino.

Davao City Mayor Sara Duterte, meanwhile, thanked the Marcos family for helping her father President Rodrigo Duterte during the 2016 elections.

The mayor said she's also grateful that some of the wedding gifts will be donated for the rehabilitation of Marawi City. — With reports from Kim Lorenzo, ABS-CBN News
