LONDON (TheDeal) -- European markets moved lower on Thursday after an inconclusive meeting late yesterday between Greek officials and its international creditors stoked further worries about a Greek debt fault and eurozone exit.

As talks resumed today, a report leaked to the Financial Times shows creditors are still demanding tough new rules governing pensions, which Greek Prime Minister Alexis Tsipras has fiercely resisted. Greece must strike a deal by next Tuesday, when its bailout funding expires and when a €1.6 billion ($1.8 billion) payment falls due to the International Monetary Fund.

Meanwhile as the possibility of a Grexit draws closer, U.K. PM David Cameron will launch his campaign to seek new European Union membership terms and avoid a "Brexit" at a meeting of European leaders in Brussels later today.

Scottish oilfield services company John Wood moved down in London after a first-half trading update in which it said profit would be down on the year before because of "challenging conditions in oil and gas market."
