A solution of codimension 2 brane is found for which 4 dimensional Friedmann
cosmology is recovered on the brane with time dependent tension, in the
Einstein frame. The effective parameter $p/\rho$ of equation of state on the
brane can be quintessence like, de Sitter like or phantom like, depending on
integration constants of the solution.
