We shall present the main ideas of the construction of a Lindelöf first countable T_1 space of cardinality bigger than continuum. This is a modification of an earlier construction invented by Gorelic. It is well-known that there are no such T_2 spaces.

The talk is going to be based on a work in progress with L. Aurichi and L. Chiozini de Souza.
