Top flight shares in London leapt for the second day in a row as oil prices rose at the end of a turbulent week for global markets.

The FTSE 100 Index was up 126.2 points to 5900, leaving the market up by 1.7% across a week that saw top-flight shares swing back and forth.

Germany's DAX was 2% up, while the Cac 40 in France was 3% higher. In New York the Dow Jones Industrial Average was up almost 100 points in early trading.

The pound was a cent up against the US dollar at just under 1.43, after official data showed that Britain's borrowing fell to a lower-than-expected £7.5 billion in December.

The Office for National Statistics (ONS) said public sector net borrowing excluding state-backed banks fell by £4.3 billion year-on-year in December, taking the overall figure to £74.2 billion for the first nine months of the year.

Sterling was two cents higher against the euro at just over 1.32.

The Footsie jumped 100 points on Thursday, after European Central Bank (ECB) president Mario Draghi assured rattled investors there was "no limit" to measures it would take to steady the eurozone area.

The ECB left its key interest rates untouched and did not ramp up its existing 1.5 trillion euro (£1.1 trillion) monetary stimulus programme, but held out the prospect of action in March which buoyed markets.

This followed the London market falling more than 3%, or 203.2 points, on Wednesday, hitting its lowest level since November 2012 on slowing growth in China as it officially slumped into bear market territory.

Trustnet Direct market analyst Tony Cross said on Friday: "It seems that it was yesterday's comments by Mario Draghi regarding further ECB stimulus that has been the game-changer - any change in this tune could quickly initiate a reversion."

Brent Crude lifted by more than two dollars to 31.44 US dollars in this session, after touching a 13-year low of 27.50 earlier in the week.

BP and Royal Dutch Shell were notable risers, lifting 10.5p to 352.7p and 69.5p to 1388p respectively.

Education giant Pearson was one of the few top flight fallers, slipping almost 2%, or 14.5p to 757.5p, after it was the biggest riser in the FTSE 100 Index on Thursday.

The group said on Thursday it would axe around 4,000 jobs as part of a group-wide cost-cutting plan.

However, broker Bernstein said on Friday the key question for Pearson remains whether demand will improve by 2018, and management "does not really know and cannot guarantee it will".

The biggest risers in the FTSE 100 Index were Sports Direct International up 24.2p at 422p, Royal Dutch Shell up 69.5p at 1388p, BG Group up 47.5p at 980.2p and BT Group up 21.6p at 487.3p.

The biggest fallers in the FTSE 100 Index were Anglo American down 21.3p at 226.7p, Glencore down 3.7p at 78.6p, Pearson down 14.5p at 757.5p and Rio Tinto down 18.5p at 1635.5p.
