JJB Sports issued the prospectus for its delayed £100m rights issue this morning, adding it represents a new beginning for the embattled sportswear group.The prospectus was approved by the UK Listing Authority last night after the company confirmed the details, which will involve issuing 400m shares at 25p each a 23.7% discount to Friday's closing price.Its main lender, Bank of Scotland, has also extended its loan facility by two years to September 2012 on the proviso that JJB raises at least £25m from the cash call.JJB delayed the issue on Friday after it became aware of rumours in relation to executive chairman Sir David Jones' personal financial affairs. It found these rumours to be totally unfounded.'The board is very concerned by the timing and concerted nature of these rumours and has passed on full details, with the results of its investigation, to the relevant regulatory authorities.' it said yesterday.
