The UK economy emerged from recession in the three months from July to September.
The economy grew by 1.0%, according to official gross domestic product figures (GDP), which measure the value of everything produced in the country.
The Office for National Statistics said that Olympic ticket sales had added 0.2 percentage points to the figures.
The economy had been in recession for the previous nine months and has still not recovered the levels of output seen before the financial crisis in 2008.
“There is still a long way to go, but these figures show we are on the right track,” said Chancellor of the Exchequer George Osborne.
