The man who fronted the rescue-that-never-was of Silverjet has seen shares in the oil and gas company he heads suspended for failing to file its accounts.

Ian Ilsley was promoted as the representative of a group of investors who said in May they were putting together a package to save Silverjet, the Luton-based business class-only airline that stopped flying last month.

In the event, the consortium - acting through a vehicle called Kingplace and backed by the Swiss trust management company Heritage that Ilsley chairs - failed to reach a deal, leading to Silverjet's 300 staff being laid off.

Now it has emerged that another company Ilsley chairs, Sandhaven Resources, has had its shares suspended on the lightly regulated Plus Market after failing to file accounts that are now more than seven weeks late.

Shares in loss-making Sandhaven, which has drilling interests in the US, floated last year at 130p. Having come back from a suspension in the spring, trading has been halted again at 32½p pending what the company called finalisation of the accounts.
