Behind the pram are her parents Elaine and Julian Smith. The couple have marched past Westminster Palace and are on their way to picnic with their family in Hyde Park where a rally awaits.

"She's been with us for all the three big demonstrations. She's happy I think," says Elaine, smiling before striding out to avoid being enveloped by the throng behind.

On February 15, more than one million people took to the streets of London to protest the then looming war on Baghdad in what police said was one of the largest demonstrations ever in the British capital.

On March 22, two days after the start of hostilities, between 200,000 and 700,000 people protested here.

At the sides of the road, Japanese tourists notice the trio and appear bemused.

The Japanese block their ears and squeeze up against a hotel to avoid being swept along as the procession winds it way through central London.

It is very loud.

Drums, hooters, the shouting of slogans by the demonstrators make it impossible to hear anything above the cacophony.

Behind placards reading: "No occupation, No War," are some of the march's protagonists: Ken Loach, the socialist English film director, Jeremy Corbyn from British Prime Minister Tony Blair's ruling Labour party.

Alongside them are members of the Stop the War Coalition who organised the march, moving at a good pace despite holding a banner.

Cameramen shoulder each other to get the best vantage point to shoot their film.

A group of students stop outside Downing Street, Blair's official residence, to lay down wreaths and flowers in memory of the women, the children and all the civilians who have lost their lives during the conflict.

"It is important we keep telling people it is not in our name. This is war for big US corporations," Loach blasts, refering to the US and British occupation of Iraq.

Demonstrators wave multi-coloured banners and flags including those of many Muslim countries. Palestinian and Iraqi flags are the most conspicuous.

There are also peace flags, Pakistani flags, Kashmiri flags and those of all the political organisations taking part in the march.

People are chanting: "We all live in a terrorist regime," to the tune of the Beatles hit "Yellow Submarine."

The march comes to an end in the abundant greenery of Hyde Park, a wooded and peaceful sanctuary in the heart of London, where the organisers intend to address the masses.

On the grass a large Pakistani family are having a picnic.

"I don't think it was worth killing so many people. This is only a war for oil," says Balqees Hamed sitting amongst her seven brothers and sisters and her father.

Mariam Termizi, a 20-year-old Malaysian law student from Kuala Lumpur, appreciates having the freedom to protest in such a peaceful atmoshphere.

Dressed modestly and wearing a headscarf to hide her hair she expresses her surprise at the behaviour of the British police who she describes as nice and in control of the situation.

Bob Cottingham, an 81-year-old pensioner, is wearing a placard as a vest which says: "bilions for bombs, peanuts for pensions."

This World War II veteran who has been decorated several times for his military valour, is now an anti-war activist who says he doesn't miss a single demonstration.

"I've done the war, I've got the medals. None of us supported Saddam Hussein," he says.
