The table below shows the final polls and the estimates made of the outcome of the General Election by members of the British Polling Council (BPC).
Collectively, these polls are the most accurate predictions ever made of the outcome of any British General Election. As can be seen from the table no estimate was, on average, more than 1.5% adrift from the final outcome, and every individual estimate was within 2% of the result for each party.
