The following comments reflect the balance of opinion we have received so far:
France had the World Cup in 1998, Spain had the Olympics in 1992, USA in 1996 and Moscow is simply not ready. Surely London is the fair choice? And as for the plans, has anyone actually seen Stratford recently? I can only pray we win the Games to clean up the east end! BACK THE BID!

When will bbc.co.uk start listening to all of us who do not want this bid to succeed? The Olympics in London will be the biggest farce and greatest expense London has ever seen and will put the Dome to shame. Why should I pay for this? Don't believe the hype - the facilities will not be for the public when this is over, they are for the University of East London. The building work required will cause delays and congestion in east London for the next seven years! The price is too high and we really really don't want it on our doorstep. A very unhappy Londoner.

I have been working on the Olympics since 1999 and I am amazed by people like Ben from East London who are so negative. It is typical of the negative British mentality and negative press, these are the first people to hail it as a success when it works and take the credit, its quite sad.

We deserve to win this bid, Great Britain has supported and taken part in every Olympic Games.

Ms Jowell seeks to drum up support for the Olympic bid in the Midlands. However, her time would be better spent in her local constituency where the world-famous Herne Hill Stadium (used in the 1948 Games)has recently closed its doors. The stadium would certainly have been used as a training centre for the 2012 athletes - particularly the track cyclists. How does Ms Jowell plan to explain this state of affairs to the panel who will decide if Londodn is to get the Games?
George Rogers, Dulwich, London
Its a great opportunity for Britain to host the Olympic Games. It will focus the UK to have a wide horizon towards the world and not be blunted in its activities from Brussels, after the event the massive security developed in buildings and people could be put to use by the prison service. Good luck to win the honour.

There's more for discussion here than just the London bid, although personally I support it. Through getting behind the core principle of the did - that sport is a desirable thing for this country to be investing in - we can send a clear message to our Parliaments that, regardless of whether we actually get the Games or not, the people of this country want to push sport up the political agenda. At a time when we are about to rebuild half of our secondary schools, this is an opportunity we may regret not pushing forward.

We still feel the benefits of the 2002 Commonwealth Games in many ways. They were expensive to host and much of the money came from Lottery funds, not local taxpayers, but it was unquestionably worth it in the long term. Let's see the bigger picture and back Britain's bid for 2012.
John, Manchester
This is all about the Labour egomaniacs making a name for themselves. Blair needs to stay here and get this country sorted out instead of swanning off to Singapore 'to boost our bid' in our name, again to make a name for himself...although maybe not the one he wants. There are far more important things going on in this country that needs their undivided attention - right now.

I understand lots of people have concerns about issues like funding and transport problems, but having looked at the bid in some detail I can honestly say it is hard to find fault with it. I think now is the time to throw our support behind the bid. Problems can be dealt with in the years to come; the chance to host the Olympics Games is too great an opportunity to squander.
Alex, Leeds
As an ex-pat English citizen, I was worried to see 2 days ago on a brief visit to London that the flag poles flying the "Back London Bid" flags in Parliament Square were toppling over in the wind. I hope civil engineers are hired to build the stadium and facilities should London be "fortunate" enough to win the bid.
Drusilla Stacy Waddy, Rome, Italy
It's really disappointing to read the reactions of devoted "regionalists" to London's bid. The UK as a whole supported previous bids from Birmingham and Manchester. Huge numbers of Londoners supported the successful Commonwealth Games in Manchester. The London Bid envisages using football grounds all around Britain, as well as many of the training centres that the visiting athletes will use. Add to that the potential opportunities for businesses throughout the UK in a London Games, and the potential for all of the UK to change their attitude to sport and physical activity. Other countries don't debilitate themselves with narrow-minded regionalism. Let's Back the Bid

Go Tessa! Hope the rest of the day goes well and the Olympic bid process too. It will be great to host an Olympic Games that the country can be proud of. Good Luck.
Mike Grieff, Fleet, Hampshire
Always touted as London's bid, not the UK bid. London area gets improvements, sports facilities, roads, rail etc - the rest of the country pays for it but gets no benefit in their everyday lives? No wonder the majority of the UK aren't backing the bid!
Lee Mayhew, York
My wife and I resent the assumption that the whole country is behind the London Olympic bid.In this part of the country, the main question is how much is it going to cost, who is going to pay,and what advantages are there going to be for those of us who live away from the South East.If London wants to stage the Games that badly, then let the people who live in the region foot the bill. After all,many past hosts of the Games are still paying for the event many years afterwards.
Tim Keefe, North Midlands
Staging the Olympic Games will be a tremendous boost for sport in London and the UK. For example, I live near the National Sports Centre in Crystal Palace Park which could come to house one of the competing nation's teams. This famous sports complex and athletics track is in much need of repair and refurbishment, probably even re-building. Such investment would leave an important legacy which would continue the current tradition and foster sport for decades to come. Local (and elite) sports people, councils, the LDA, other authorities and local residents have been working together to form a consensus on what is needed - we are ready for the challenge.
Ray Sacks, Near Crystal Palace Park
Could you tell me what Derbyshire will get out of the London Olympics and how much we'll be expected to stump up for it? I ask again as neither your department nor the 2012 website team have bothered to reply to this question which I asked last year.
Geoff Wilkinson, South Derbyshire
I do back the bid,simply that transport in the United Kingdom is a joke. How can you expect vistors to wait for trains that never arrive and tail backs on roads? Living close to the QE2 bridge /Dartford Tunnel it will be jammed solid for spectators coming from the south to north.

There is plenty of publicity about supporting the Games but where can one register one's lack of support for them?
Richard Smith, Fleet (Hants)
How much will it cost me and my family (of 4)to travel to the London Olympics, see one day's sport, stay overnight in a London hotel and return travel say by train? This why it is the London Bid and not the Uk's bid.

I find it sad that so many comments on here highlight the inferiority complex held by non-Londoners towards the capital. People in the south east didn't try to scupper the Manchester Olympic bids in this way. The Olympics is a celebration of national pride and achievement, hence we will all benefit from the 'feelgood factor' it would bring, it is so much more than being just about money.
Andy Smith, Watford
When Birmingham and Manchester made their bids for the Olympic Games, there was very little support forthcoming from London. Steve Ovett even supported the Paris bid against Birmingham's. Why should we support this bid which is successful will only widen the gap between the South East and the rest of the country?
Andrew Hackitt, Birmingham
Im very pro the Olympic bid, about time really but I do have one concern. What are the plans to ensure that our already over burdened transport system is able to cope with the huge increase in pressure?
James Rogers, Bedford
I have only been to London twice, both times it was dirty, smelly and (some) of the people were very rude. I say to the IOC, Paris or Madrid would be better. And why should I pay for something I don't want and cannot see how I would benefit from. Sack the Bid!!!
Scott Sellers, Leeds, England
Squash should be included in the sports for the olympic Games, will you fight for inclusion?
Christine Raywood, Cheshire
This is not a question. Most Scots oppose a London Olympic bid for two reasons. Scotland will not benefit from any economic spin-off and sport in Scotland will directly suffer because funding will be cut to sports bodies to pay for the London games. It is a Lose-Lose situation for Scots, we can only hope the Paris bid is successful.
