Nevanlinna theory for meromorphic functions on $${\mathbb{C}}_ p$$ has been studied by Hà Huy Khoai. In the present paper the two fundamental theorems are proven for all meromorphic functions. As a consequence a p- adic analogue of the Malmquist-Yosida theorem is found. The proofs are similar to the complex case (and easier). There are no examples to show that the second inequality $$\sum \delta (\alpha)\leq 2$$ is best possible.
