MPs are to consider a letter from Sports Direct boss Mike Ashley agreeing to be questioned about his company, as long as the politicians visit the firm's head office first.

The Business Select Committee has been trying to quiz Mr Ashley for months about working practices, including the use of zero hours contracts.

He has repeatedly refused to attend the meetings, at one stage said the MPs involved were "a joke".

In a letter he said he will travel to Westminster, but only on condition that the MPs visit the Sports Direct offices in Shirebrook, Derbyshire, the day before.

He has offered to fly the MPs to Derbyshire in his helicopter.

The committee will discuss the letter at its meeting next week.

Earlier this month it was announced that English league bosses planned to hold talks with Mr Ashley over his interests in Rangers.

He holds an 8.92 per cent stake in Rangers in addition to his ownership of the Magpies. He also owns a 49 per cent share of the company selling Rangers' retail products.

The businessman would have to get the written consent of the Football League if he is to hold on to his Rangers interests.

If they refuse, he may be forced to loosen his grip on the retail deal that reportedly earns Rangers just four pence from every pound spent in its club store.

Meanwhile, Mr Ashley also faced the prospect of being ordered to pay the legal fees of the Scottish Football Association and Rangers chairman Dave King after he dropped court action involving the two.

In April the Sports Direct founder abandoned his legal case in which he was challenging the SFA's decision to class Mr King as a "fit and proper person" for involvement with the Ibrox club.
