The trial of Lord Archer was dominated at times by talk of diaries.
There were also photocopies said to be of 1986 diaries and diaries for 1985, 1986 and 1987, which Ms Angela Peppiatt, Archer's former secretary, produced in court.
The prosecution said there were three diaries involved in the charges faced by Archer - two were genuine and one was a fake. Only one was known to be still in existence - the genuine one which Ms Peppiatt had kept, and which she handed to police in 1999 .
The other two were produced in court during his libel case against the Daily Star, then returned to Archer. They had since disappeared.
Diary One: The genuine Dataday appointments diary kept by Ms Peppiatt at Conservative Central Office. She retained this after she stopped working for Archer.
The prosecution said Archer kept this diary secret during the libel proceedings and that it contained an entry for a meeting with Terence Baker, Archer's film agent, on the evening of September 9th, 1986.
Mr Baker told the libel trial that he met Archer by chance in a restaurant on September 8th, and was given a lift home by him, effectively giving Archer an alibi for the time he was accused of having been with Ms Coghlan.
Diary Two: The fake appointments diary, an A4 diary which was used in the court case. Only two pages were visible and the reference to Mr Baker was not there.
Ms Peppiatt told Archer's trial that he had approached her with the blank 1986 diary in early 1987 and handed her a list of entries which he told her to copy into it.
Diary Three: The Economist working diary kept at Archer's flat on Albert Embankment, central London. Archer was cleared of a charge that he added appointments to that diary in 1987 to "bolster" his case.
Ms Peppiatt told the court she made photocopies of the diaries before and after the entries were made because she realised she was getting involved in a "deception".
