UK stocks are expected to open flat on Friday morning as market pause for breath ahead of a quiet day, with investors awaiting a pivotal weekend for Greece.
City sources predict the FTSE 100 will open four points lower than Thursday's close of 6,630.47.
"With only tier-2 data releases in the calendar, Greece is likely to be at the centre of attention ahead of the referendum on Sunday," said analysts at Danske Bank.
Nevertheless, news flow on Greece is likely to remain quiet, given that the government has confirmed that a referendum will go ahead as planned on Sunday, and that creditors have refused to discuss a bailout deal until after the public vote.
According to the head of the Hellenic Chambers of Commerce, Constantine Michalos, cash reserves at Greek banks were down to just 500m. Although banks were expected to reopen next week, Michalos said: "Anybody who thinks they are going to open again on Tuesday is day-dreaming. The cash would not last an hour."
The Markit/CIPS UK services purchasing managers' index is likely to be the main event of the day for the City and comes on the back of mixed PMIs on the construction and manufacturing sectors earlier in the week. Analysts expect the PMI to have risen to 57.5 after falling to a five-month low of 56.5 in May.
Meanwhile, equity markets in the States will close early for a long weekend as the country holds its Fourth of July celebrations.
