LONDON, May 24 (Reuters) - Britain's top share index rose on Tuesday, helped by well-received trading statement from Kingfisher and a broker upgrade for Imperial Brands.
Britain's top share index was up 28.20 points, or 0.4 percent, at 6,164.63 by 0802 GMT, having opened the day slightly lower.
Kingfisher rose 2.1 percent, among top gainers after the owner of the B&Q chain reported a 3.6 percent increase in like-for-like sales in the first three months of its financial year. Traders said its UK and French divisions had performed better than expected.
"In its first half-year, it is a little early to be judging the returns from the five-year 'One Kingfisher' strategy but management is pleased with progress so far," David Stoddart, analyst at Edison Investment Research, said in a note.
Tobacco firm Imperial Brands rose 2 percent, benefitting from an upgrade by Barclays to "overweight" from "equal weight".
"Imperial is executing strongly. Organic sales momentum is improving and margin/cash generation increases underpin (at least) 10 percent dividend growth," analysts at Barlcays said in a note.
"Moreover, we are increasingly confident margins will surprise to the upside and that the US is performing ahead of expectations."
Top faller was Coca-Cola HBC, down 3.2 percent after a shareholder said it was going to sell its 1.5 percent stake in the bottling company.
