Sources said though Congress has decided to field candidates for the posts of mayor and deputy mayors in the three municipal bodies, it may review the decision in consultation with parties like BSP and INLD.
The elections for mayors and deputy mayors in the three municipal corporations will be held on April 28 and 29.
Sources said a decision to open channel of communication with other "secular parties" was taken at a meeting of senior Delhi Congress leaders presided over by DPCC chief Arvinder Singh Lovely.
They said names of candidates for mayors and deputy mayors have already been finalised and will be announced on Monday, the last day of filing nominations for the elections.
"Congress has decided to do everything possible to ensure the defeat of BJP. We are in touch with all secular parties," Chief spokesperson of Delhi Congress Mukesh Sharma said.
