“Voters must be given the opportunity to express freely their democratic choice,” Brussels said on Friday in a statement, ahead of the Dhaka and Chittagong polls on Apr 28.
The 28-nation bloc also called all sides to refrain from any actions that could spark “further violence” in Bangladesh.
The corporation election has apparently put to rest the more than three months violent blockades as the BNP-led alliance endorsed their candidates.
The BNP boycotted the general elections last year and launched a campaign in January that has left more than 120 people dead and many hundreds more injured, mostly in firebombing.
But its chief Khaleda Zia’s motorcade was attacked allegedly by the ruling party activists in the last week.
The EU said: “We look to political leaders to create favourable conditions for peaceful, inclusive, transparent and credible elections to take place.”
“All political actors should take concrete steps to end violence, de-escalate tensions and engage in a constructive manner, for the long-term stability and democratic development of Bangladesh,” read the statement.
