UK stocks begin trading on the back foot after near eight-week highs yesterday.

Elsewhere in the resources space, a bullish exploration update from Kenya sees FTSE 100 oil explorer Tullow Oil (TLW) edge 1.1% higher to 729.5p. The Etom-1 well in the northern part of the Lokichar basin has discovered 10 meters of net oil pay extending the proven oil basin northwards. The Amosing-2 and Ngamia-3 appraisal wells further south were also successful and will boost the prospects for accelerated development of South Lokichar which has 600 million barrels of discovered resources.

But Iraq-based oil firm Gulf Keystone Petroleum (GKP:AIM) slumps 10% to 74.2p as its 40,000 barrels of oil equivalent per day 2014 production target is threatened by in-country violence.
