The FTSE 100 rose 1 per cent to 6,897 - its highest in 14 years - while the euro jumped 0.12 per cent, to 1.31 dollars. Investors also piled back into Russian equities, with the Micex leaping 2.59 per cent on the news. The rouble rose 1.72 per cent against the dollar.

As a result of my telephone conversation with Russian President we reached an agreement on a permanent ceasefire on Donbass.— Петро Порошенко (@poroshenko) September 3, 2014
In recent days the conflict between the two countries has escalated, with Russia said by Nato to have sent "well over 1,000 troops" into the region to fight alongside pro-Russian rebels.
Yesterday, the International Monetary Fund warned Ukraine could need up to $19bn of bailout money if fighting continued at current levels throughout 2015.
The announcement comes ahead of a two-day meeting between Nato leaders in Wales.
The summit, which begins tomorrow, will focus on strengthening partnerships between members, although crises in Ukraine and Afghanistan are on the agenda. Members are expected to back plans to create a rapid-response force.
