Oil prices slipped again today thanks to political uncertainty in Greece and rising crude stocks in the US, which raised fears of a decreasing global demand for oil.

Brent crude fell 50 cents to $112.23 a barrel, dropping for a sixth straight session, its most sustained fall in 24 months.

US crude fell 66 cents to stand at $96.35 a barrel, as domestic crude stocks rose 7.8 million barrels in the week to 4 May, according to the American Petroleum Institute.

Investors are awaiting the release of US Governmental data later today, reported Reuters.
