The FTSE 100 fell 13.56 points this morning, as uncertainty over Greece began to affect the market.

Britain’s top share index is set for its first decline in five days, breaking its three week winning streak. Whilst European stocks have suffered over the past week of Greek negotiations, the FTSE has so far avoided the backlash and continued to perform well.

“It’s fears as to what happens next with the Greek debt bail out talks that are spooking the market. Last night’s divergence between the two sides has clearly rocked sentiment,” said Tony Cross, market analyst at Trustnet Direct.

“Although the downside in London may be looking quite limited right now, the picture is far worse on the continent.”

A Greek deal looks increasingly unlikely before the Saturday deadline imposed by creditors. If Greece default on their loan and exit the EU, global markets look set for a difficult few months.
