The British government has invested heavily in the arts in recent years. Now it’s time to go to the next level, writes Nicholas Serota. “We are confident we are attracting a growing audience, and can make a significant contribution to the success of the 2012 Olympics, when the eyes of the world will be on us. We want to show what the cultural sector has achieved in the past 10 years – and what it could achieve if the sort of investment it has received under this government is sustained. We want to get across our values, and our vision – and make sure they really are part of the government’s, and the country’s, core script.”
