Is there any karaha (dislike) in the Imam of Eid Salah being a different person to the khateeb?
بِسْمِ اللهِ الرَّحْمنِ الرَّحِيْم
In the name of Allah, the Most Gracious, the Most Merciful
It is preferred that the khateeb (the person who performed the khutba) leads the prayer. However, if someone else leads the prayer then the prayer will also be valid inshallah.
Only Allah knows best
