I've been looking at the National Audit Office report which says the HS2 high-speed rail project has an "unrealistic timetable".
It was written before the Brexit vote, so it doesn't speculate on what effect, if any, it could have on HS2.
The Department for Transport's very keen to send out a "business as usual" message, promising that planned investment in our roads and railways won't suffer.
MPs are due to vote on phase one of HS2 later this year. If they approve the bill, that's effectively the green light to start building the line from London to Birmingham. And MPs approved the project overwhelmingly the last time they had a vote.
