Asset managers Ashmore (ASHM) and Aberdeen Asset Management (ADN) open 3% and 2.2% higher and trade at 278p and 418p respectively.

Red tape software suite supplier Ideagen (IDEA:AIM) rallies 11.6% to 38.5p as it raises £17.5 million to buy Gael, a software company supplying the healthcare, manufacturing and aviation sectors.
