B&Q owner Kingfisher has named Danish retailer Michael Loeve as the new boss of the DIY chain as it steps up an overhaul and battles against sliding sales.

Mr Loeve, 41, will join as chief executive of B&Q UK and Ireland in September from Coop Danmark - one of Denmark's biggest retailers with around 1,200 stores, where he is group retail director.

He replaces Kevin O'Byrne, who left last month.

Mr O'Byrne is said to have lost out in the race for the top job at B&Q's owner Kingfisher to Veronique Laury, who took over from Sir Ian Cheshire in December.

Mr Loeve takes on the role at a challenging time for B&Q as it sees sales come under pressure and as the wider Kingfisher group embarks on a swingeing shake-up under Ms Laury, who is axing 60 B&Q stores over the next two years impacting around 3,000 jobs.

There has even been speculation that the group might plan to phase out the B&Q brand name.

Sales at B&Q in the UK and Ireland fell 1.1 per cent on a like-for-like basis in the 13 weeks to May 2.

But the group said B&Q was up against strong comparatives from a year earlier, when like-for-like sales rose 9.7% thanks to a later Easter and good weather.

Kingfisher said Mr Loeve has solid experience of business overhauls.

The group said: "Michael is an experienced retailer, with 12 years' experience in senior roles across retail operations, supply chain, IT and strategy.

"He has a strong track record of leading successful business transformation, through focusing on customer needs whilst remaining close to the operations."

Mr Loeve oversees five retail brands at Coop Danmark and previously headed up its 250-strong SuperBrugsen chain as managing director.

He also worked at Copenhagen Airports for a two year stint, as vice president of operations, until 2011.

Ms Laury said: "He is an experienced retailer who will form an important part of the new diverse international team we are putting together at Kingfisher. I look forward to working with him."

Mr Loeve added: "Home improvement is a great market with huge potential and B&Q has a strong position within it, however there is more that we can do to maximise its strengths.

"With a better and more unique offer at good prices where customer needs come first, all backed by the scale of a unified Kingfisher, we will transform and grow B&Q, helping our customers to have better homes and better lives."
