UPDATE: Graham Stewart, author of the volume of the History of the Times (which I've read, and has been used as a prop in an AS film this year!), has hit back at Evans' claims, strongly arguing that Murdoch's was the only credible bid, without which both Times papers might have gone bust (much as he argues in the book).
Not a new story, Leveson was quite withering on Murdoch's apparent inability to remember a meeting of questionable legality with Thatcher that seemed to ensure his Times bid wasn't sent to the Monopolies and Mergers Commission. There are parallels with the Murdoch meetings with Conservative ministers decades later when his bid to buy up remaining BSkyB was suspiciously waved through, only for Hackgate to torpedo this, and ultimately lead to Leveson, part of his brief being to investigate improper relationships between press and politicians.
The news hook - aside from a left-wing paper seeking to raise a right-wing spectre at election time - is the revised 5th edition of Harold Evans' excellent book on the press, a great read for a wider view of the press, and a useful counterpoint to Curran and Seat on, given Evans was a Tory-supporting Sunday Times editor.
