Ramsden, who was jailed for ten months in 1987 and is still appealing the conviction, is investing £1.5m in a £10m share placing.
He will also have options to buy another 60 million shares subject to the approval – and emergency general meeting – of Hansard shareholders on 19 August.
The options would enable Ramsden to double his stake in the company.
Ramsden was jailed for hiding assets from creditors following the 1987 Japanese stock market collapse. He has created several businesses this year, including securities trading system Private Treaty Market and Griffin Leisure Ltd, which Hansard is in the process of buying.
