Shares of BP PLC UK:BP -0.98% BP +0.90% posted some of the biggest losses in the index, down 1%, as oil prices slipped below $93 a barrel.

The broader losses for the U.K. index came as investors paused for breath after a strong rally in the new year on the back of a budget agreement in the U.S. to avert the fiscal cliff.
Banks, however, also rose on Monday. The Basel Committee on Banking Supervision on Sunday decided to delay the implementation of stricter capital requirements by four years.

Outside the main index in London, shares of Balfour Beatty PLC UK:BBY +0.42% gained 0.5%, after the infrastructure firm said it has received a contract to build a gas-fired power plant in Delaware. See: Balfour Beatty gets pact to build U.S. power plant.
