I Have Never Left UMNO

I overheard over Buletin Utama while blog surfing Pak Lah's speech. The line that attracted me was ....saya tidak pernah meninggalkan UMNO...... Oh, is that so? Maybe I am wrong. Did he left UMNO and join Semangat 46 with Tengku Razaligh. Semangat 46 is not UMNO. So that means Pak Lah lied that he never left UMNO.
