Rules


Output can be given by any convenient method.
You can print it to STDOUT or return it as a function result.
Either a full program or a function are acceptable.
A single trailing newline is acceptable, but no other formatting changes are allowed.
Capital letters are required.
Standard loopholes are forbidden.
This is code-golf so all usual golfing rules apply, and the shortest code (in bytes) wins.
Haskell, 53 bytes



[tail$do c&lt;-reverse a;' ':[c|c&lt;=d]|d&lt;-a]
a=['A'..'Z']

This uses that each line has exactly 25 spaces. So, instead of separately handling the prefix spaces and the spaces between letters, we take 26 spaces, and decide whether to put a letter after each. This unfortunately gives one extra leading space, which we remove.
