The present work deals with a dark energy model with two scalar fields. Such a model has been proved to be successful in providing a model for in ation in the early universe. With two scalar fields, one has a better handle on the model parameters. The ultimate motivation is to use this freedom to construct a model which can drive acceleration both at early and the late time acceleration. The present work shows that the basic requirement is fulfilled, the model has a late time acceleration in the presence of pressure less uid.
