The UK government has launched an investigation into the takeover of F1 by American tycoon John Malone's Liberty Media.
Bernie Ecclestone said last week that the takeover is in fact not yet complete.
And it may not be for some time yet, with British government department the Competition and Markets Authority (CMA) announcing an "inquiry" into the Liberty deal.
The CMA is responsible for strengthening business competition and preventing anti-competitive activities.
A preliminary decision is expected in early 2017.
Meanwhile, two potential candidates to get involved in F1's post-CVC future have played down claims they may accept roles.
Gerhard Berger welcomed Liberty's involvement but told Austrian Servus TV: "No, I'm not in the group, I don't have the time."
And Red Bull mogul Dietrich Mateschitz told Spain's Marca sports newspaper: "That would be a big challenge, but I have a job that takes up all of my time as well as many other obligations and interests."
