a spokesman for Ms Harman said the meeting had "nothing to do with the contents" of the statement.
"The content of the Speaker's statement is entirely a matter for the speaker," he said.
"The purpose of the meeting is to discuss the parliamentary business and handling of issues that arise from the fact that the Speaker's statement and the Queen's Speech will be happening on the same day."
However, BBC political correspondent Reeta Chakrabarti said: "Harriet Harman details in the e-mail several principles she sees as vital, including that MPs must be able to do their work and that they are not above the law; matters that would appear to be central to the issues the speaker must discuss."
How very unlike the BBC to give the public the facts that show that one side is right and the other wrong in an ongoing political argument. BBC "balance" usually involves making both sides look equally valid.
