Bishop of Willesden Pete Broadbent said the run-up to the vote on Britain's membership of the EU was "a game with no game plan and no rules of conduct".
In his blog the clergyman also comes out in support of a remain vote.
Bishop Pete accuses the Prime Minister David Cameron of calling the referendum "for all the wrong reasons" and only doing it to deal with a split in the Conservative Party.
Mr Cameron, he said, made a promise but has "no plan for what happens on 24th June if we vote to leave".
"What has happened is detrimental to politics and the political process," he said.
"Both sides have used misleading figures and information to conduct an argument that has been more like a childish spat in the playground than a measured examination of the issues.
"The electorate have been fed with ever more cooked statistics and exaggeration. It's virtually impossible for the average voter to discover some facts."
A distrust of politicians had led to a campaign of "fear, misrepresentation, and paranoia" he warned.
Bishop Pete added he was "completely unconvinced by the Leave Campaign and will be voting to Remain".
He's the latest in a long line of bishops to back a remain vote.
Lord Carey, the former Archbishop of Canterbury, is the most high profile churchman to back a leave vote.
