The FTSE 100 looks set to break the 6,200 level, the first time since May 2008, continuing the rally that has propelled markets since the beginning of the year.
Although the UK's leading share index closed flat yesterday, it had already moved to 6,193 in early trading, a gain of 14.27 points or 0.2%.
Spreadbetters predict the index will rise 20 points in total today, following a strong session on Wall Street due to positive corporate earnings and a lift from Google in after-hours trading as it reported Q4 profits rose to $2.8bn.
Unilever was the strongest share in the FTSE, rising 2.28% to 2507p after it reported double digit growth in emerging markets led to underlying sales growth for 2012 of 6.9%, beating estimates of 6.5%.
United Utilities (+1.67%), Randgold Resources (+1.58%), BHP Biliton (+1.27%) and Evraz (+1.14%) were also among the top performing stocks of the morning.
Across the pond, the S&P 500 closed up 0.44%, or 6.58 points, at 1,493.
