Both Manor and Caterham are included on the FIA's official entry list for 2015, even though the futures of both teams are highly uncertain.

Indeed, many of Marussia's assets were sold at auction last week, though the all-important entry slot is still up for grabs.

Caterham, which was the subject of a crunch meeting earlier this week as administrators seek a buyer, is also shown on the entry list, though, like Manor (Marussia) the entry is marked "subject to confirmation".

That said, the Lotus entry also features an asterisk even though both drivers are confirmed and the team, backed by Genii Capital, has an agreement to use Mercedes power units.

Also, it appears that Lewis Hamilton will get his wish and race with the number 44 as opposed to 1, whilst Sebastian Vettel is given preference (in the order of entries) over teammate Kimi Raikkonen, likewise Fernando Alonso at McLaren.
