Shares in Burberry surged by as much as 7% in London on Wednesday after the luxury retailer reported strong sales over the holiday season.

Burberry is considered a market leader in its online branding and sales strategy. The retailer has been particularly successful in Asia, where it continually reports double-digit revenue increases.

Albizua said Burberry's click-and-collect offering, which allows customers to buy items online and collect them in-store, probably helped drive sales in the quarter.
