No other countries need to either approve or deny the deal and let's not forget the FTC has been sitting on this and has been waiting to say if they will go ahead and block it and approve it plus if it does get blocked by the FTC then Microsoft is within its rights to sue the FTC or take the FTC to supreme court and try to fight this deal hence this is not over yet. Also, it's said that Microsoft hired lawyers in the UK to fight this to get this deal overturned and approved. So it's not over with.
