Interesting, I read Paper Tiger, written by Alide Dasnois and Chris Whitfield, two ex IOL staff from its better days who were kicked out due to not complying with Iqbal.
They mentioned in the book that the DA's gripes with IOL extended from their days. DA was on their case to attack them even when IOL was a trusted source of news.
I don't see what reasons Dasnois and Whitfield will have to lie about that.
Anyway, an interesting book.
This article by Whitfield covers it a bit.. Tony Leon is reported to have been telling people not to buy the Cape Times and the Cape Times was a good paper at that time.
