The full weight of the Greek saga made its presence felt on Footsie at the close as traders pondered whether a debt deal really will be struck this weekend.
Its international creditors have given the country a weekend deadline to reach consensus with the Eurozone ahead of market open on Monday. Otherwise, it risks defaulting on a €1.6bn repayment due to the IMF on June 30 (Tuesday).
Another meeting starts again tomorrow as any thoughts of a quiet, restful weekend for officials concerned has been blown out of the water.
It will be the fifth Eurogroup meeting in nine days.
Chris Beauchamp at spreadbetters IG noted: "The week ends much as it began, with Greece at the top of the agenda.
"It appears that we were too eager last week to declare that Greece had entered the last chance saloon; this weekend is the final opportunity for a deal. Despite the failure to hammer out an agreement, eurozone indices have still made gains on expectations that a deal will be struck.."
FTSE100 closed the day around 54 points down at 6,753.
