Its not going well for the Home Secretary and The Speaker

The immediate inquiry may not be held for months

On Wednesday Mr Martin pledged a "speedy and immediate" inquiry but it has now emerged it may not begin until after the police leak inquiry ends.
"It might not meet for months," shadow commons leader Theresa May told MPs.
Commons leader Harriet Harman said it would not be "wise" to set up a probe while police inquiries continue.
Meanwhile Home Secretary Jacqui Smith has been giving a statement to MPs on the arrest of shadow immigration minister Damian Green and the search of his Parliamentary offices.
She has reiterated that she did not know the arrest of an MP was pending and if she had, it would have been "wholly inappropriate" to get involved.
But she was attacked by her Tory shadow Dominic Grieve who said that was "utterly flawed" and asked her: "Who is in charge of the police, if she isn't?"
