In a move that calls into question the future role of "tsars" and other politically appointed civil servants shadow technology minister Alan Duncan said Pinder's role could be replaced if the Tories come to power.
"It should either be a proper civil servant or agency. To have someone half-way in between is unsatisfactory," he said.
Labour defended the e-envoy's record. "The key things with the role of the e-envoy are that people listen to him, he has access to ministers and that he oversees the UK's e-revolution." Andrew Pinder is doing that, a spokesman said.
A recent report from the Commons trade and industry select committee said that the UK's e-commerce strategy could be damaged unless the e-envoy's role is re-defined.
MPs expressed concern that the office is "simply an extension of Whitehall".
