The TNS poll revealed that undecided voters are beginning to switch to Leave as the crucial final weeks of the campaign get underway. The poll of 1,222 voters gave Leave 41 per cent to Remain’s 38 per cent, in a sign that the Project Fear campaign waged by the PM and other EU supporters has badly backfired.
It is the first time the pro-Brexit camp has been ahead in a TNS poll and showed support for Leave climbing five points while backing for Remain fell one per cent.
Luke Taylor, head of social and political attitudes at TNS UK, said: “This poll suggests that we are seeing movement from undecided voters towards the Leave camp, though we will need to wait until the next poll to see if this is a trend or random variation.
“Although this poll is the first time that we have seen a lead for Leave, the race remains very tight. With five weeks to go until the referendum it remains all to play for.”
