The late Queen Elizabeth's coffin was taken along the Royal Mile in the Scottish capital Edinburgh on Monday in a silent and solemn procession watched by thousands of people paying their respects to Britain's longest serving monarch.

The oak coffin, draped in the Royal Standard of Scotland and with a wreath of white flowers placed on top, was then carried into St. Giles Cathedral and the crown of Scotland laid on it.

While a grieving crowd - with many people in tears - stood outside, King Charles and other members of the royal family, as well as political leaders and dignitaries, attended a service of thanksgiving for the queen.

The coffin will lie in St Giles' Cathedral for an overnight vigil before being flown to London on Tuesday.

Queen Elizabeth died on Thursday in her holiday home at Balmoral, in the Scottish Highlands, at the age of 96 after a 70-year reign.

Charles became king on her death and was formally proclaimed as monarch on Saturday.

The queen's coffin arrived from Balmoral on Sunday and stood overnight at the Palace of Holyroodhouse, the monarch's official residence in Scotland.

A bagpipe lament was the only sound as kilted soldiers from the Royal Regiment of Scotland bore the casket from the palace and placed it in the hearse for the short journey to the cathedral.

A gun salute boomed out from a battery on Edinburgh Castle when the hearse moved off and a single round was fired each minute of the procession up the historic street. Other than that there was just silence - except a brief shout from a heckler aimed at Prince Andrew.

Under a sunny sky, King Charles and his siblings - Anne, Andrew and Edward - walked slowly behind the hearse, while the Royal Company of Archers provided the guard of honour.

At the service, Scotland's First Minister Nicola Sturgeon read from Eccliastes and folk singer Karen Matheson sang a psalm in Gaelic, while other speakers paid tribute the late queen.

Earlier on Monday in London, King Charles had addressed members of the British parliament at Westminster Hall.

He called parliament the "living and breathing instrument of our democracy" and pledged to follow his late mother's example in maintaining its independence.

As with all the ceremonies taking place to mark the queen's death and Charles' accession to the throne, there was much pageantry.

He arrived at Westminster Hall to a fanfare of trumpets with his wife Camilla, Queen Consort. The royal couple sat on ceremonial chairs, with cavalry troopers in red tunics and plumed helmets standing to attention behind.

Charles, 73, told members of the House of Commons and the House of Lords: "While very young, Her late Majesty pledged herself to serve her country and her people and to maintain the precious principles of constitutional government which lie at the heart of our nation. This vow she kept with unsurpassed devotion.

"She set an example of selfless duty which, with God's help and your counsels, I am resolved faithfully to follow."

The assembly then sang "God Save the King".

On Tuesday, the coffin will be flown to London, where on Wednesday it will begin a period of lying in state until Sept. 19 - the day of Elizabeth's state funeral - on a catafalque at Westminster Hall.

In London, members of the public will be allowed to process past the coffin, which will be covered by the Royal Standard with the sovereign's Orb and Sceptre placed on top, for 24 hours a day until 6.30 a.m. (0530 GMT) on Sept. 19.

The government said those wishing to do so should expect to queue for many hours and possibly overnight due to the number of people expected.
