BP weighs on main bourse after Q3 results

* Hunting slides after profit warning

Oct 29 (Reuters) - London's stock markets eased on Tuesday as the prospect of a Brexit 'flextension' and parliament rejecting Prime Minister Boris Johnson's demand for an election before Christmas kept investors guessing and wary of taking more risk.

The FTSE 100 was 0.1% lower by 0807 GMT, pulling back from a near one-month high in the previous session. The mid-cap FTSE 250 was also marginally lower.

Oil major BP weighed the most on the main bourse, dropping nearly 1% after posting a sharp drop in third-quarter profit on the back of weaker oil prices and lower production.

Oilfield services provider Hunting fell as much as 7% to the bottom of the FTSE 250 in early deals after a warning on profits as it struggles with a slowdown in the U.S. onshore drilling market. (Reporting by Muvija M and Shashwat Awasthi in Bengaluru; editing by Patrick Graham)
