Markit's purchasing managers' index for the construction sector was expected to show a small slide to 52.7 in May after 53.1 back in April. This is the second PMI after yesterday's manufacturing one that came out at 56.7, within expectations.

GBP/USD was trading around 1.2860 ahead of the publication. Resistance awaits at 1.29, followed by 1.2980 and 1.3050. Support is at 1.2775.

The most important PMI is on Monday, for the services sector. However, the focus of markets is around the UK elections. Every poll counts.
