“Criminal proceedings have now commenced and it is extremely important that there should be no reporting, commentary or sharing of information online which could in any way prejudice these proceedings.”

A spokesman for the Conservative Party said they believed that those charged had "done nothing wrong".

They said: “The legal authorities have previously cleared Conservative candidates who faced numerous politically motivated and unfounded complaints over the Party’s national Battlebus campaigning.

“We continue to believe that this remaining allegation is unfounded. Our candidate has made clear that there was no intention by him or his campaigners to engage in any inappropriate activity. We believe that they have done nothing wrong, and we are confident that this will be proven as the matter progresses.

“The individuals remain innocent unless otherwise proven guilty in a court of law. The press, parties and those on social media should be aware of the provisions of the Contempt of Court Act and the strict liability rules against publishing anything which would prejudice the course of justice.

“There is a broad consensus that election law is fragmented, confused and unclear, with two different sets of legislation, and poor guidance from the Electoral Commission. Conservatives are committed to strengthening electoral law to tackle the real and proven cases of corruption that were exposed in Tower Hamlets in 2015.”
