Spending a bit of time this morning researching newspapers that were publishing in London in the 1930s.
I’m thinking of using The Daily Mirror as the oppositional newspaper to Annie Coleson’s work at The Sunday Times.
From the Wikipedia article on The Daily Mirror
Leigh Brownlee went into newspapers and he is picked out as one of the senior figures representing the Daily Mirror at the funeral of the newspaper’s then editor, Alexander Kenealy in 1915. Brownlee was himself editor of the Daily Mirror from 1931 to 1934, though this was a difficult period for the newspaper, which had fallen significantly from its achievement of the first one million circulation in 1918 because of price cutting by rival newspapers. The Mirror was sold by Lord Northcliffe in the mid-1930s and Brownlee appears to have left then: the newspaper relaunched as an American-style tabloid after he left. He went into partnership in a news agency, but the partnership was dissolved in 1936.
