What was a volatile day on the markets ended rather flat.
Big European Central Bank (ECB) and Opec meetings in Vienna failed to move the FTSE 100 far in either direction and it ended down 0.1 per cent at 6,185.61 points.
The ECB decided, as expected, to keep interest rates on hold. Though it did raise growth and inflation forecasts for the euro zone, but by less than some had hoped.
De facto Opec leader, Saudi Arabia, promised not to flood the already oversupplied oil markets but the one-time cartel was unable to come to an agreement on production policy.
"We will be very gentle in our approach and make sure we don't shock the market in any way," the kingdom's new energy minister, Khalid al-Falih told reporters.
Joshua Mahony, of IG, said:
Opec and the ECB have led a highly volatile day today, as initial positivity turned sour at the decisions from both parties to remain as they were.
Upward revisions to growth and inflation for 2016 certainly made a change from the usual fare, potentially marking a turning point after a sustained period of pain.
