DISGRACED peer Jeffrey Archer is facing another inquiry into whether he had broken prison rules – by promoting his latest book from jail.

The former Tory Party deputy chairman gave an interview to USA Today from Hollesley Bay open prison, near Woodbridge, after the newspaper passed a list of questions to him via his agent.

Sons of Fortune, his 11th novel, is already on best-seller lists in Britain and the U.S. after being published last month.

A Prison Service spokesman said last night the Hollesley Bay governor was "aware of the article and will be examining whether or not this contravenes prison rules".

Archer, who was jailed for four years for perjury in 2001, admitted breaching strict prison guidelines by identifying other inmates and their crimes in his controversial book, A Prison Diary.

Last September the millionaire novelist got into trouble for using a home visit to attend a champagne party held by former Tory Party colleague Gillian Shephard.

Days later a prison officer resigned and an off-duty policewoman was left facing a professional standards investigation after it emerged they had also lunched with Archer while he was on day release.

In the interview, Archer said he had no computer access in prison and handwrote everything.

He provided fellow inmates, who called him Jeffrey, with advice on literary and political matters, rather than offering them legal help.

Archer said he worked out at the prison gym twice a week and spoke to his wife Mary "every day".
