Perhaps UMNO is a anagram of MUON?
A MUON is an unstable lepton common in cosmic radiation.
Well UMNO is certainly unstable and very common, perhaps not cosmic, but most certainly comic, and definitely as dangerous as radiation.
To break it down further let's look at the lepton.
A lepton is any member of a class of subatomic particles that only respond only to electromagnetic force, weak forces and gravitational force and are not affected by strong force.
Leptons are said to be elementary particles; that is, they do not appear to be made up of smaller units of matter.
Leptons can either carry one unit of electric charge or be neutral.
Each of these types has a negative charge and a distinct mass.
So that brings things together, a Muon is a negatively charged lepton, an dense elementary particle not made up of smaller units, responsive to gravitational and weak forces, unaffected by strong forces.
UNMO can certainly be charged as being negative, base, and a stubborn, dense, minute mass which seems to be unmoved by strong opposition, but is responsive to weaknesses and will undoubtedly suffer from the forces of gravity and fall in due course.

The Main Asteroid Belt

Perhaps NAJIB is an anagram for BAJIN?
Bajin is a main belt asteroid discovered on 25th November 1997.
Well Najib has a main belt, which can be observed to be getting bigger by the day; and he like an asteroid, is not living in the real world.
UMNO is an unstable and common insignificant particle, which only responds to electromagnet force, weak forces and gravity!
Whilst NAJIB is, it seems, condemned to outer space from where oblivion is inevitable.
