Supercars worth millions of pounds brought London to a standstill as a secret club of self-confessed 'boy racers' held a procession through the heart of Westminster in tribute to the victims of last month's terror attack.

A gold-plated Bentley, a Lamborghini and a Ferrari were among the glamorous vehicles that were driven in unison past the Houses of Parliament.

The procession was organised by the Piccadilly Boy Racers, a group which has previously caused chaos in the capital as pedestrians and tourists stop the high-end sportscars in their tracks to take photos and selfies.

Ahead of the event, the club of businessmen and entrepreneurs told MailOnline it wanted to speak up' against terrorism and 'bring people of all race and religion together as a symbol of peace, love and unity'.

As the motorcade passed the Palace of Westminster - from where Khalid Masood launched his murderous rampage that killed six - the drivers got out of the vehicles for several seconds to lay bouquets of flowers.

The road was brought to a standstill for several minutes as the drivers and their passengers got out of their cars to lay bouquets of flowers

Several police officers could be seen remonstrating with the drivers to move their vehicles as passers-by flocked to take photographs of the brightly-coloured procession.

However organisers said conversations they had with police were amenable and officers even helped them to carry out their tribute.

The club is run by brothers Kash and Shabs Ahmad, from Ilford, Essex, who only let those with high-end supercars join the group.

Shabs told the MailOnline: 'Following recent attacks in Westminster which cost the lives of innocent civilians as well as PC Keith Palmer, we felt it was only right to pay our condolences and show our love by standing united to oppose the atrocious acts of violence.

'We felt that being British Muslims with a platform, we wanted to speak up against such acts and bring people of all race and religion together as a symbol of peace, love and unity.

'[We want to] recognise the efforts of the Met Police, emergency services and the nurses and doctors who ran across Westminster bridge from St Thomas to assist.

'This is something which touched our hearts as my brother Kash is a sufferer of Crohns disease who very nearly lost his life in 2012.

'The doctors at St Thomas saved his life and it was on that very bridge he learnt how to walk again after suffering from paralysis from below the waist. Any one of us could have been a victim that day.'

In an interview with MailOnline last year, Kash, who runs car company Kream Developments with his brother Shabs, denies that the group are 'flash'.

The procession comes on the day that the body of PC Keith Palmer, the police officer killed protecting Parliament by Masood, was placed inside the Palace of Westminster ahead of his funeral tomorrow

He said: 'When we were young it was our ambition to be "boy racers" – now we are men, we have achieved that and are proud we can afford these kind of cars.'

The procession comes on the day that the body of PC Keith Palmer, the police officer killed protecting Parliament by Masood, was placed inside the Palace of Westminster ahead of his funeral tomorrow.

PC Palmer will rest for 24 hours in the Chapel of St Mary Undercroft, before he is taken to Southwark Catherdral at 2pm on Monday for a full police funeral.

The honour, which requires the consent of the Queen, is normally reserved for heads of state and senior politicians such as Baroness Thatcher and Tony Benn.

Unarmed PC Palmer, 48, was stabbed to death in the terror attack on March 22, when he tried to stop Muslim extremist Khalid Masood running into the Palace of Westminster armed with two knives.

The largest-ever gathering of British police officers will assemble in London for his funeral. Upwards of 5,000 men and women from every force in the UK are expected to line the route to Southwark Cathedral for the service.

Changing cubicles are being provided for the officers, who have been advised not to wear their uniforms when travelling to the funeral.

An estimated 50,000 members of the public are expected to join them in paying tribute to the murdered constable.
