Which option best suits the MVP model

While I was refactoring some code I had a doubt.

If some error happens in the model class, would it be better to call a method of the model class from the presenter class to check if something went wrong, or instead call a method of the presenter class from the model class when the error happens?

For example: Call a method of a model class (from presenter class)

if (modelClass.isWhateverRight()) //Do something


Call a method of the presenter class (from model class)

if (something) presenterClass.showMessage();

Sorry for the very bad explanation, thanks!
