Jacques Rogge will fly in to London for talks with Prime Minister David Cameron this week as the International Olympic Committee's final inspection of the 2012 Games preparations takes place.
Rogge, the IOC president, will meet Cameron on Wednesday morning at the start of a two-day inspection by the IOC's co-ordination commission that is likely to conclude with another pat on the back for London 2012 organisers.
The talks are not focused on any specific issue - an IOC spokesman described them as a "tour d'horizon" to discuss general preparations - but it will probably be the last meeting at this level before the Games take place.
The IOC have no burning concerns, saying they believe the organising committee are "doing an excellent job", but the inspection visit will be a chance for LOCOG, with less than four months until the start of the Olympics, to deliver final assurances that everything is on course.
All the major venues are completed and are now being fitted out, there have been unprecedented ticket sales - though plenty remain to be sold for the Olympic football tournament, and the last programmes to get ready for July 27 are now being rolled out.
British IOC member Sir Craig Reedie believes the co-ordination commission will find little to concern them.
He said: "I would expect the IOC co-ordination commission to check the final delivery systems for the various client groups, including sponsors, and I would be surprised if there was any question that London could not give a good answer to.
"Arrangements to date are as good as can be."
London 2012 has proved to be a smooth experience for the IOC after Beijing in 2008, where the political system and bureaucracy proved to be troublesome even if the facilities were all completed well ahead of time, and Athens in 2004 where the delays and procrastination drove the IOC to distraction.
By the time of the final IOC inspection in Athens, only 94 days before the start of their Games, the roof of the stadium was still not fully in place and co-ordination commission members were alarmed to see the sections of it that were in place were wobbling.
