Reporting from the inquiry
As Boris Johnson starts with an apology, and protestors are removed from the inquiry room, it's worth looking back at Baroness Hallett's early comments about press leaks.
Before Johnson started giving evidence she said in a statement that she wanted to remind "all those involved in the inquiry process that they must maintain this confidentiality".
"Until a witness is called and appears at a hearing, or the inquiry publishes the witness's statement, it's meant to be confidential between the witness, the inquiry and the core participants."
Many of the details of Boris Johnson's 200-page witness statement were published over the weekend in both the Times and Telegraph newspapers. The BBC also reported on the key points which Johnson was planning to make.
