USERS of auction site eBay could be brought to the attention of tax collectors and excise agents, experts are warning.

London investment manager Nick Train describes eBay as "part of the black economy" and warns that it will not be long before it is subject to government intervention.

He said: "If the company continues to grow at current rates, sooner or later, it is going to impinge upon the consciousness of tax collectors and excise agents around the world."
