WH Smith led the second tier risers’ as its shares jumped almost 6%, or 21p to 395p, after it said it was on course to meet profits expectations. Like-for-like sales were 6% lower on the high street, but the retailer made up the difference with an increased focus on margins.
LogicaCMG moved in the opposite direction, down 5%, or 9.25p to 173.5p, after it said the growth rate in its IT services branch was seen at below 5%, under than the guidance from analysts.
Back in the top flight, British Airways shares continued to fall, down 5.5p to 530.5p, amid the threat of strike action from cabin crew members as part of a dispute over pay, staffing and sickness absence.
And shares in More Than insurer Royal & Sun Alliance lifted 1.75p to 163.5p after a US Court dismissed a General Motors complaint against the group. The US car maker was suing the group for about £500m (€762m), alleging it had not been reimbursed for asbestos-related personal injury claims.
