This week the Leave campaign takes the most narrow of leads among definite voters, making gains among all respondents whilst narrowing the expectations gap to an all-time low.

Building on last Monday’s poll gains, the Leave camp now leads among those definite to vote on referendum day, according to the ORB’s latest poll for the Telegraph.

Leave has increased its vote share by two points to attract 49 per cent of definite voters compared to Remain’s stagnant 48 per cent, reversing its net position from a one-point net negative position last week.

Unlike last week, however, Leave’s gains have now also translated to the trend among the electorate as a whole, suggesting that last week’s figures were a reflection of a broad change among public attitude and not just a fleeting bump in the poll numbers.

Forty-four per cent of all respondents (both those who are certain of voting and all others) now say they are intending to vote for Brexit in just over a weeks’ time, a notable increase of 4 points, while 49 per cent say they will vote to stay in the EU, a three-point fall.
