China is preparing for a major change in its top political leadership in the autumn, with President Hu Jintao and other senior leaders stepping down after 10 years in charge.

President Hu has overseen a decade in which China has become the driving force of the world's economy.

The country's middle class has grown from 50m to 300m during Hu's tenure, and there has been a big increase in the number of millionaires and billionaires too.
