With just hours to go before polling opens in the EU referendum, an ITV News/ComRes poll suggests 17% of voters are still undecided about whether they will vote Remain or Leave.

The new poll suggests Remain is on 48% and Leave is on 42% - a six-point lead - with don't know at 11%. That compares to an 11-point lead for Remain in a ITV News/ComRes poll conducted last month.

A poll for The Sun conducted by ComRes last week suggested the lead for Remain had narrowed to one point.

After don’t knows are accounted for, Remain leads Leave by 54% to 46% in the latest poll.

More than four in five voters (82%) have definitely made up their mind about which way they are voting, while 17% say that they may still change their mind, according to the poll.

It also suggests claims by the Leave campaign about what would happen if Britain voted to leave the EU seem to have had more cut-through among voters than claims made by the Remain side.

In particular, the main Leave claim that ‘we can take back control’ has had the greatest impact, with 44% saying it made them more likely to vote Leave, versus 38% who say it made no difference.

However, overall the poll suggests voters are most likely to say that claims on both sides of the campaign have had no difference as to which way they will vote.
