Valmiki Ramayana Ayodhya Kanda Sarga 19 Shloka 24

कैकेयि O Kaikeyi, त्वम् you, मम in my affair, ईश्वरतरा सती even though capable of exercising greater authority, राजानम् to the king, यत् अवोचः for which you pleaded, मयि in me, किञ्चित् even a little, गुणम् virtue, न आशंससे do not expect, नूनम् this is certain.

Since in my case you have exercised more authority (than my father) and pleaded with the king, it follows, you, for sure, do not see any virtue in me, O Kaikeyi (Or else, you should not have asked for Bharata's kingship).
