A group including the entrepreneur who led an aborted rescue deal last year are demanding the issuance of shares that they claim would convert into control of the company, Sky News learns.

Deepening tensions over the ownership of Yodel, one of Britain’s biggest parcel delivery businesses, were exposed on Thursday when a group of purported warrant-holders indicated a desire to seize control of the company.
Sky News has learnt that a group said to comprise dozens of warrant-holders - including the entrepreneur who led an aborted rescue deal for Yodel last year - has served a formal demand for shares they claim to be entitled to.
Sources close to the group, which includes Jacob Corlett and Mark Pearson, a venture capital executive at Fuel Ventures, claimed on Thursday that issuance of their equity would lead to them owning more than 70% of Yodel's shares.
The latest move in an increasingly bizarre confrontation raises fresh questions about the future of a delivery firm whose key customers include New Look, Gousto and eBay.
Yodel's website says it employs up to 12,000 people during peak trading periods and 10,000 throughout the year.
Tensions over the company's performance and direction have intensified over the last year, with loss-making Yodel on the brink of administration last February.
A rescue deal fronted by Mr Corlett - founder of a rival business called Shift - was announced, with him briefly joining Yodel's board.
However, the proposed takeover subsequently collapsed, and has sparked legal claims by each party against the other.
Mike Hancox, Yodel's chief executive, then gained control of Yodel with financial backing from the London-listed company Paypoint and Independent Growth Finance, a specialist lender.
A Yodel spokesman said on Thursday: "We utterly refute the validity of these purported warrants, copies of which were not received until yesterday.
"Yodel has no record of these warrants in its legal records.
"These warrants have been received from two entities who are parties to a high court claim issued by Yodel in which serious allegations with regard to breach of fiduciary duties and misappropriation of company funds are made.
"Judge Logistics Limited remains the 100% shareholder of Yodel and there is no change of control at Yodel."
