LONDON, March 2 (Reuters) - Europe's FTSEurofirst 300 index retreated from a seven-year high on Monday, with Tullow Oil down on concerns that it could be dropped from Britain's blue-chip index after a quarterly reshuffle and Vivendi falling after a stake disposal.
Greek banks also came under pressure from lingering concerns over its debt repayment plans.
Tullow Oil slid 6.8 percent to feature among the top fallers on the FTSEurofist 300 on concerns the stock could be replaced on Britain's FTSE 100 index by Hikma Pharmaceuticals this month, traders said.
"Investors are worried that a likely drop from the FTSE will prompt tracker funds and some exchange-traded funds to sell Tullow Oil shares to reduce their weightings," Jawaid Afsar, trader at Securequity, said.
