(ShareCast News) - Kingfisher, which owns B&Q, said it delivered a solid second-quarter sales performance to date across all its major businesses, albeit against softer comparatives than in the first quarter.In its pre-close update for the 10 weeks to 11 July, the company posted a 4.8% rise in total sales at constant currency, or 3.5% in like-for-like terms.Kingfisher said the pilot of its unified IT system, which is a key enabler of new chief executive Véronique Laury's 'ONE' Kingfisher plan, started on time in Ireland."We look forward to updating on further progress against our first 'sharp' decisions in September. And we have to date returned £138m to shareholders via a share buy back since the year end," said Laury.In the UK and Ireland, same store sales were up 5.5% compared with 1.6% in the first quarter, while in France, they rose 1.3%, versus 1.2%.The company said Screwfix was on track to have opened 11 new outlets during the second quarter, taking the total to 412.Richard Hunter, head of equities at Hargreaves Lansdown Stockbrokers, said: "Kingfisher has built on the progress announced at the first quarter update, with a statement which implies rapid progress is being made."He added: "The shares have staged something of a recovery more recently, now having risen 9% over the last year, as compared to a 2% dip for the wider FTSE100. If this level of progress can be maintained in the following quarters, the long standing market consensus of the shares as a weak hold may need to be positively revised."At 09:44, Kingfisher shares were up 1.3% at 371.90p.
