The Senate of the Philippines on Monday adopted a resolution expressing profound sympathy over the passing of Queen Elizabeth II of the United Kingdom of Great Britain and Northern Ireland.

Senate President Juan Miguel "Migz" Zubiri, who introduced and sponsored Senate Resolution 198, said the Queen's most enduring quality was her duty to her people.

Queen Elizabeth II died peacefully at her Scottish estate on 8 September at the age of 96. Zubiri said the Queen lived in grace and dignity and was a constant figure of stability for her people.

"She ushered in a golden age of the monarchy. Her unflappable leadership was instrumental in uplifting national morale even in times of socio-economic and political upheaval," he said.

"In her seven decades as a monarch, she oversaw the strengthening of their foreign affairs, including bilateral relations between the UK and the Philippines, particularly with peace and development, disaster relief and management, trade investments and climate action and health," he added.

The resolution was also introduced and co-sponsored by all of his colleagues in the Upper Chamber.

According to the resolution, the passing away of Queen Elizabeth II, an outstanding world leader, would always be remembered by the Filipinos for her invaluable support and contribution to the Philippines.

The resolution stated that diplomatic relations between the Philippines and the United Kingdom were established on 4 July 1946, during the reign of Queen Elizabeth II's father, King George IV. Both governments worked to foster stronger political, economic and cultural ties, it added.

Among the earliest agreements entered into by the Philippines and the United Kingdom during Queen Elizabeth's reign was the Agreement on Air Services, relating to the designation of routes, and the Philippine-United Kingdom Agreement on Air Services Between and Beyond their Territories.

Both agreements were entered into on 31 January 1955.
