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.”
