Marks & Spencer has carved out a new role for Stuart Rose's executive assistant to lead the retailer's massive online drive into non food next year.

John Dixon will take up the new post of director of e-commerce from 1 January.

M&S's online relaunch in spring 2007 will include a vastly improved functional website and fulfilment offer due to its collaboration with market leader Amazon.

At the company's interim results, Rose said he had set Dixon the target of growing internet sales from £100m to £250m "in a couple of years".
