Churches around the UK will hold remembrance services for the Queen on the first Sunday after her death.
The Church of England has provided parishes with special guidance on services during the mourning period.
The organisation urged churches to toll bells and open for prayer and special services after the announcement of the Queen’s death on Thursday.
The Queen was formally the Defender of the Faith and governor of the Church of England, titles dating back to Henry VIII and before that have now passed to her son.
The Queen said her religious faith was a big part of her personal life and King Charles has also described the role his own faith plays in his life.
Meanwhile, later today, the formal Proclamation of King Charles III, as the King of Gibraltar, will take place. But the thoughts of many here are still with the Queen.
“Honestly to God, we loved her,” sisters Rosemarie and Lydia tell me.
They, like many Gibraltarians, hold a deep affection for the late Queen. Her Majesty’s visit to the British overseas territory, in 1954, is etched into the collective memory as well as the landscape.
One of its main roads was renamed to Queensway while Queen Elizabeth II’s royal cypher can be seen on the gates of the Alameda Gardens.
In an address on Friday the Chief Minister of Gibraltar, Fabian Picardo, said: “Gibraltar was her Rock, and she was ours.”
The Rock, as it’s sometimes known, lies at the southern tip of the Iberian Peninsula and has a population of over 33,000 people. Spain has a long-standing claim on the densely populated rocky outcrop but local voters have twice, in 1967 and 2002, overwhelmingly voted to remain British.
“We’ve always been considering ourselves British citizens,” says Rosemarie.
“We are Gibraltarian but we are proud to be under the Queen, now under the King.”
