The UK's economy grew by 0.3 per cent in May, helped by the royal wedding and warm weather.
The latest assessment by the Office for National Statistics (ONS) marks a change in the way the UK's GDP is calculated.
From now on, the ONS will release a monthly indicator and a rolling three-month figure.
Previously, it only put out growth data every three months.
In the three months to May, the economy grew by 0.2 per cent compared with the previous three-month period.
