Rothschild advised Trinity Mirror in the sale and the price was set in accordance with Berkshire Regional Newspaper's revenues in 2006.
The Berkshire Media Group, a subsidiary of The Dunfermline Press, will assume control of the 14 titles, which includes the Reading Chronicle series.
This sale comes just a month after Trinity Mirror sold 25 of its south-eastern regionals to Northcliffe, a branch of the Daily Mail & General Trust, for £64m. The set included East Surrey and Sussex Newspapers and Kent Regional Newspapers.
Last week Trinity Mirror's chairman, Sir Ian Gibson, was made chairman of the supermarket chain Morrisons.
