Downing Street has said it remains possible to publish the Gray report before the weekend, and it would hold discussions with the Commons Speaker if it was received during the weekend.
The Prime Minister’s official spokesman said: “It remains hypothetically possible to still publish it today or tomorrow.
“We have committed to publishing in the House, I think hypothetically it is not a requirement under the terms of reference, obviously we would want to do so at the earliest possible opportunity but we are not in control of at which point we are in receipt of the report.”
Asked what would happen if No 10 received it on Friday night, he said: “We would need to make a decision in conjunction with the Speaker about what he thought was acceptable, obviously balancing the significant public interest in having sight of the report.”
Downing Street has said it has not seen the Sue Gray report, a summary of it, or received any indication of what it contains.
The Prime Minister’s official spokesman said: “No sight whatsoever.”
He also said the PM has not spoken to the police in the parties investigation.
