PMI Construction data are due at 11:30 (GMT+2). The indicator is expected to fall to 52.9 points in December from 53.4 points a month earlier. The indicator assesses the state of business activity in the construction sector. It is built upon polls of managers of major UK construction companies to estimate current economic situation in this sector and the prospects of its development. Values above 50 are a positive signal and strengthen GBP. Values below 50 weaken it.
