Abstract
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 of equation of state on the brane can be quintessence like, de Sitter like or phantom like, depending on integration constants of the solution.
