Communications technology firm Spirent Communications was heavy faller after it cautioned that overall growth in the second half may reduce to mid- to low-single digit increase amid ongoing macro-economic uncertainty. High-flying Ophir Energy also disappointed the market as it revealed its gas discovery at the Papa-1 well off the coast of Tanzania is likely to contain lower recoverable resources than it had hoped for. Leading the upside was industrial property group SEGRO after saying that pre-tax profits gained 5.3% in the first half despite net rental income falling by 3.4%. The firm also reported today that it has completed the sale of a portfolio of 10 non-core UK industrial estates for £110m.
