Yes, that will be the old British 5A type of plug, judging by its size relative to the others.
The U.K. 5A plug differs from the Continental 2-prong plug in that the prongs are slightly shorter, slightly thicker, and set slightly closer together. (C-H, the old British 2A plug is considerably smaller than this one).
I wouldn't be at all surprised to find it still installed as standard in some African countries.
As David said, modern shaver outlets are generally designed to accept British, European, American, and Australian plugs for the benfit of travelers (many also provide both 120 and 240V via the built-in isolation xfmr).
There are some outlets still in use in older properties which were designed only for the British 5A plug though. European plugs will go in though with force, especially if the plug has the softer type of molded plastic which allows the pins some movement.
Compare this with my photo at the top of this thread -- The plug at the bottom right is a 2-pin 5A type.
