Evgeny Lebedev, chairman of Independent Print Ltd, said: "I hope that this will mark a great new era for these remarkable newspapers, which have such a distinguished record of great journalism. It is my intention to help The Independent to prosper under new management and most importantly for it to continue to pursue journalism of distinction and impartiality.
