The FTSE 100 index of leading UK company shares finished June largely flat at 7,661.77, down slightly from 7,678.20 points at the end of May, a decrease of 16.43 points or 0.21% during the month. The Office of National Statistics (ONS) has revised up economic growth in the first quarter of 2018 from 0.1% to 0.2%. The moderate increase was a result of construction output declining by 0.8% in the first quarter, a smaller decrease than the 2.7% that was expected due to the severe cold weather.
