The Tricolore has lit up Trafalgar Square, County Hall opposite the Westminster Parliament and Tower Bridge in support of the rally for unity in Paris.
Thousands of Londoners also assembled in sympathy on the same day as the largest demonstration in the history of France attended by heads of state including the Prime Minister.
The Francophile atmosphere in Trafalgar Square is set against the backdrop of the blue cockerel on the fourth plinth- often seen as an unofficial symbol of France.
In London the singing and chants echoed those heard in Paris.
A shrine of pens, pencils, ‘Je suis Charlie’ banners and Charlie Hebdo cartoons was created in memory of the victims of this week’s attacks.
It’s estimated several thousand people gathered in central London to sing the French National anthem, and chant slogans for liberty, democracy and freedom of expression.
The French interior ministry has speculated three million people turned out in Paris.

He said that the march was inspirational and he and other world leaders agreed it was important to tackle the poisonous ideology behind the murders.
The slogan shared by many was ‘Je suis Charlie, je suis flic et je suis juif’ in memory of the victims of shootings by extremists this week.
Most of the victims were journalists and cartoonists working in the satirical magazine Charlie Hebdo. Three were police officers.
Those killed included a caretaker, four people in a Kosher supermarket and the three islamist extremist gunmen.
The Deputy Prime Minister Nick Clegg was in London’s Trafalgar Square and told Londonmultimedianews reporter Katie Callin that the terrorism threat to Britain would be reduced if there was less conflict in the Middle East.
In London there was a carnival atmosphere. One protester held a fist high in front of Nelson’s column wearing a paper bag declaring ‘Je suis Charlie, Ahmed, Flic, Juif, Republicain…’
Ahmed was the forename of the Muslim police officer executed when the brothers Cherif Kouachi and Said Kouachi made their getaway from the Charlie Hebdo headquarters.
Flic is a slang term for police in French.
The blue, white and red of the French republican flag, the Tricolore, was projected on famous London landmarks.
It covered each wing of the National Gallery building on the north side of Trafalgar Square and was reflected in the water flowing in the fountains.
The Mayor of London, Boris Johnson said the people of London stand shoulder to shoulder with Paris.
The light shows at a simultaneous London rally were intended to show solidarity.
The French Embassy in Britain thanked Boris Johnson for organising the support in London.
Earlier Deputy Prime Minister Nick Clegg signed the book of condolence at the French Embassy.
Gestures of support have been displayed all over Britain- from the union jack flying at half mast over the Palace of Westminster…
to a flag of France also half mast outside a village post office.
