UK stocks fall in early trade on Monday as oil prices plunge after global producers failed to agree on an output freeze to address the supply glut. The FTSE 100 index nudges around 15 points lower, or about 0.2%, to 6,328, with midcaps and smaller companies also off but by even more modest levels.

The fairly predictable failure to secure a oil price freeze deal in Doha (17 Apr) nonetheless undermines crude again with resulting pressure on oil and gas stocks. BP (BP.) dives 2.2% to 348.2p and Royal Dutch Shell (RDSB) falls 2.75% to £17.69.

Mining stocks are also southbound in early trading with a raft of hole diggers in the red, led by Antofagasta (ANTO), off 2% at 461p.

British Gas parent Centrica (CNA) says it is on track to meet its targets for this year reducing its direct headcount by around 3,000 and reporting adjusted operating cash flow of more than £2 billion. The statement comes alongside a first quarter update showing 800 jobs losses already. But the market is not impressed, marking the shares 2.3% down at 232.9p.

Greetings cards maker International Greetings (IGR:AIM) sparks up 10.6% to 172.5p on a positive year-end trading update, a possibility flagged by SHARES in this week's small caps section of the magazine.
