A Formula One Grand Prix on the streets of London may have moved a step closer after the Government announced new powers for local authorities to stage motor races on public roads.
David Cameron unveiled the move as he opened Williams' new F1 engineering facility in Oxfordshire, saying it would mean "more races, more events, more money coming into our country".
He said: "We're going to change the rules so that local councils are able to make the decision so you don't have to have a private member's Bill through Parliament, which we think will be great news for British motor sport."
The Prime Minister also hailed the F1 industry, saying it was "an amazing success story, eight of the 11 teams based here in the United Kingdom, 41,000 people working in the industry in the Oxford area alone, working for about 4,300 companies".
London Mayor Boris Johnson has signalled he is ready to support the idea of a Monaco-style Grand Prix on the streets of the capital.
The former headmaster of a prep school London mayor Boris Johnson attended has been arrested on suspicion of historic sex assaults.

A computer and documents have been seized by police investigating the claims against Mr Williams, who was released on police bail and has not been charged.
A Sussex Police spokesman said: "Officers investigating allegations of historic sexual abuse at a school in East Sussex have arrested a local man. The 69-year old was arrested at an address in Barcombe on Wednesday July 9 on suspicion of sexual assaults and child neglect.
"A computer and documentation were seized for examination. After being interviewed, the man was released on police bail on the same day until November 11, while inquiries continue."
Labour leader Ed Miliband is the latest politician to be caught out on the cost of everyday items after he struggled to name the average cost of a weekly shop for a family, during an interview with Good Morning Britain.
David Cameron was tripped up last year when he claimed the price of budget supermarket bread was "well north of a pound", when at the time it was 47p.
He later claimed he did not know the price because he had a breadmaker at home.
London Mayor Boris Johnson told BBC presenter Jeremy Paxman that a pint of milk cost "about 80p or something like that".
Shortly after being elected Liberal Democrat leader, Nick Clegg was challenged by a caller on an ITV News local show about how much state pensioners received. The Deputy Prime Minister said "about 30 quid" when the figure at the time was £90.70 a week for a single person.
Boris Johnson and Nick Clegg have been recognised as unlikely radio stars at an industry awards ceremony.
The Mayor of London and the Deputy Prime Minister - together with presenter Nick Ferrari and the rest of their LBC production team - were given the title for the "innovative strand" of programmes for their phone-in shows featuring the pair.
Mr Johnson joked: "Well this is absolutely absurd. Of course I know I'm not really the recipient - I'm like an overweight Belgian tourist being propelled to the summit of this Everest by the skills of superior Alpinists, our LBC production team.
"I'd like to thank the efforts of the great Sherpa, Clegg, and the people of London who have listened in their dozens and called in, and to my fellow overweight Alpiniste, Nick Ferrari."
The Radio Academy judges praised the team behind the shows for placing politicians "front of mic, hosting their own show, on a regularly scheduled basis, something never before attempted on UK radio".

The judges' citation praised the team behind the shows for placing politicians "front of mic, hosting their own show, on a regularly scheduled basis, something never before attempted on UK radio".
London Mayor Boris Johnson has claimed the treatment of a veteran BBC radio DJ, who quit because he accidentally played a song with the N-word in it was "utterly disgraceful".
Speaking to The Telegraph, London Mayor Boris Johnson said Britain was living in a "Boko Haram world", in reference to the terrorist network that kidnapped over 200 schoolgirls in Nigeria.
"There is certainly no logic at the BBC. They should restore Mr Lowe to his job - if he will take it - and the entire BBC board should go down to Devon to apologise in person, and at their own expense."
He added: "Their treatment of this man is utterly disgraceful".
Old Routemaster buses were in operation around the capital today as Transport for London attempted to keep London moving during the Tube strike.
TfL said there was a record number of buses on the capital's roads after 266 extra buses were brought in for the first day of the 48-hour walkout.
David Cameron described travel disruption caused by the Underground strike in the capital as "unacceptable" on Twitter.
It's unacceptable that millions of people are having their lives disrupted by today's Tube strike in London.
A 48-hour Tube strike has created "total chaos" for Londoners just trying to get to work, one commuter has said.
Emily Toner told ITV London that she was forced to hire a Boris bike because of the crowds at Liverpool Street station:
When arriving at Liverpool Street at the Tube, I discovered the gates were still not open so I resorted to using a Boris bike to get into work.
Total chaos has been caused to good people just trying to get to work.
