Ruling party-endorsed candidate Khokon along with Salim conducted mass contact programmes in Hazaribagh and Kamrangirchar areas of the capital on Saturday.
Khokon, the son of former mayor of undivided Dhaka Corporation late Mohammad Hanif, is vying for the mayoral post with his electoral symbol ‘hilsa’.
Independent MP Salim during day-long canvassing told reporters, “I am with Sayeed right now and will be with him in future too.”
Khokon promised the residents of the areas to fulfil their expectations if elected.
Both ruling party leaders were flanked by other party leaders and activists during the campaigning on Saturday.
The elections for the Dhaka South, Dhaka North and Chittagong City Corporations are slated for Apr 28.
Haji Salim had collected the nomination papers to run for the mayor post of DSCC. But he withdrew after the Awami League decided to extend its support to Sayeed Khokon.
Khokon, however, went to meet Salim at his house a day after submitting the nomination form. They later announced to work together.
