Dark matter, the major component of the matter content of the Universe,
played a significant role at early stages during structure formation. But at
present the Universe is dark energy dominated as well as accelerating. Here,
the presence of dark matter has been established by including a time-dependent
$\Lambda$ term in the field equations. This model is compatible with the idea
of an accelerating Universe so far as the value of the deceleration parameter
is concerned.
