London markets are struggling to make up their minds in early trade on Tuesday, seemingly taking in stride unease in the euro zone in the wake of the Greek elections but tentative over UK growth figures due later today. The FTSE 100 nudges 3.5 points lower in to 6,850 having risen by a similar token from the off, although British mid caps put in a stronger showing thanks to a handful of upbeat trading updates. The FTSE 250 index moves 35 points north to 16,505.

Wall Street firmed overnight while Asian and key European markets are mixed. Oil continues its weak run, WTI crude off 0.5% to $44.92/bbl with Brent crude down 0.6% to $47.86/bbl.

But the biggest collapse of the day comes at oil explorer Afren (AFR). The west Africa-based energy company sees its shares tumble more than 52% to 8.41p after revealing the extent of its financing squeeze, indicating a major debt restructuring will be needed without a fresh funding injection, or the mooted takeover by Nigeria's Seplat.

The shares rise 4.2% to 388.1p.

A falling Brazilian Real hangs heavy over transport group Ocean Wilsons (OCN:AIM), prompting a profit warning. The shares slide 4.9% to 965p.

But telecoms services, kit and software specialist Gamma Communications (GAMA:AIM), one of Shares 15 for 2015 picks at , jumps 5.7% to 268p as it reveals strong trading that will see full year 2014 revenue and adjusted EBITDA slightly beat market forecasts that were pitched at around £169 million and £22 million respectively.

A drop in fourth quarter selling prices leaves investors disappointed with Gem Diamonds (GEMD:AIM), down 3.9% to 162.5p. This echoes a similar reaction to Petra Diamonds' (PDL) trading update yesterday where it flagged a weak outlook short-term for the diamond market.

Soft drinks group Britvic (BVIC) adds 4.9% to 677.5p on a reassuring first quarter update.

Pub owner and brewer Marston's (MARS) edges up 1.6% to 149p on a 2% increase in like-for-like sales during the 16 weeks ending 24 January.
