The past week saw London's Olympic 2012 victory overshadowed by terrorist attacks on the transport network. What are your thoughts on these events?
Coming the day after London's joy in winning the 2012 Olympics, a victory largely achieved from showing the passion of youth and the magnificent diversity of our capital, the events of Thursday were particularly hard to take.
London seemed a quieter place the morning after, with fewer people on the tube and train, but there also seems to be a quiet determination not to let such depravity break our spirit or our unity. I am sure we will recover. Londoners of all colours and creeds are determined to go forward together and that is certainly the message in all I have read and heard since the blasts.
Andy Walker, 41, communications director, London The bombings were a vile and evil event carried out by a minority group of cowardly scum.
We should pay tribute to all who helped in the aftermath. Well done to the people of London who have picked themselves up and carried on as usual. While we still have the ability to do this then terrorists will not win.
Robert Pike, 43, project manager, Exeter My thoughts and prayers are with all those affected.
The coincidence of G8 and London winning the 2012 bid is a headline-hitting time for the terrorists. It will not stop the capital working and we all need to be vigilant about what is happening around us. London's 2012 Olympic Games is great news. Let's do it better than any other Olympic capital by delivering to time and budget.
John D Brownlie, 56, project director, Shrewsbury The Olympics will give a massive boost to the economy; we can only hope that the planning system can turn around projects expediently. It does not have to take 19 years of studies to conclude that Crossrail, Thameslink 2000 and the Thames Gateway are needed.
Other countries achieve faster procurement. The only response to terrorism is no response;
business as usual, or they win.
John Sreeves, 47, senior bridge engineer, Swindon This demonstrates the harsh cruelty of life - up one day and tragically down the next.
Rob Andrew, 40, policy manager, Cornwall One has to be pleased that we have won the Olympics and it can only be good for east London as well as the country in general. As to the sad events of last week - it was almost expected.
Trevor Odell, 44, technical specialist, Surrey What a difference a day makes.
Like it or not Tony Blair has made decisions which have affected the lives of billions of people not only in this country but across the world. The decision to make a strong bid for the Olympics has paid off although the consequences of failure were insignificant. The decision to go to war has been less than successful with the consequences of failure likely to affect the lives of many far beyond the 2012 Olympics.
Charles Brewerton, project engineer, Brighton Talk about a contrast from one day to the next. I honestly think that the dastardly attack will serve to unite us more to enjoy the fruits of the 2012 Olympics.
