The PM's official spokesman has released a statement, with what appears to be a change of mind.
During his Commons statement earlier, Boris Johnson resisted calls - including from his own MPs - for him to promise to publish Gray's full report, once the police have finished their investigation.
Now his spokesman says: "At the end of the process, the prime minister will ask Sue Gray to update her work in light of what is found.
"He will publish that update."
The spokesman adds: "The prime minister is clear we must not judge an ongoing investigation and his focus now is on addressing the general findings.”
A reminder: The Met Police said today their investigation would not take more than a year, but did not give an exact timeframe for when it would wrap up.
