Tower Hamlets returning officer John Williams says more police will be at polling stations to stop fraud.
At least six police officers will be on duty at each of the polling stations.
Councillor Peter Golds said: "I want to see the police ensure that anyone can enter a polling station without hindrance from groups of people trying to canvass them as they try to go in."
He added: "I also want the police to ensure that when people are inside the polling stations voters vote unhindered and people are allowed to cast their vote in private."
