Dumfries and Galloway Council have lowered the flag to half mast, in recognition of Margaret Thatcher's funeral.
As the hearse arrived at St Clement Danes, the coffin was taken into the church, ready to be transferred to a gun carriage to be taken to St Paul's.
The flags outside the Scottish Parliament building are flying at half mast this morning to mark the funeral of Margaret Thatcher.
Scotland's First Minister Alex Salmond is in Westminster to attend the ceremony.
The Scottish Conservative leader, Ruth Davidson, will also be among more than 2,000 guests at St Paul's Cathedral.
A debate on Margaret Thatcher's legacy which was due to be held at Holyrood today, was rescheduled for tomorrow after the Scottish Conservatives branded the timing "provocative and insensitive".
The Queen's former press secretary Dickie Arbiter told Daybreak that the Queen "can't win either way" whether she decided to go to Margaret Thatcher's funeral or not.
He said: She's criticised because she's going, in some quarters and she would have been highly criticised if she hadn't have gone.
"She's going because she wants to go because she wants to pay respects to somebody who was a Prime Minister for 11 years, some pretty turbulent years, we remember the Falklands war, we remember the industrial unrest, but we came out of it all.
"She's going there along with 2,000 other people to pay her respects."
A tattoo artist from Lady Thatcher's hometown Grantham has paid a life-long tribute to the 'Iron Lady' by having her head tattooed on his leg.
Louis Maier aged 32 wanted to have the six-inch work of art on his right calf to honour her.
The unusual design features Baroness Thatcher's head sitting on an ice cream cone complete with a flake.
The reason Mr Maier chose the colourful design was to mark Lady Thatcher's work as a research chemist prior to her political career.
During her time as a chemist she was part of a team said to invent the technique of pumping air into ice cream to produce a soft scoop version to reduce production costs.
Two funeral workers have been sacked from Co-operative Funeral care for cremating the wrong body.
The mix-up saw staff place the wrong body in a coffin and send it to Birtley Crematorium in Gateshead, Tyne and Wear.
Grieving friends and family, who thought they were saying their final goodbyes to someone they loved, were actually saying farewell to a complete stranger.
Co-operative Funeralcare have apologised to the family, and sacked the two workers involved. A spokesman said:
A serious breach of our strict procedures occurred and following a thorough investigation two members of staff have been dismissed.
Once the issue came to light, we immediately notified the families concerned and apologised for any distress caused and we have liaised closely with the crematoria. We remain in close contact with the families.
