Increasing number of voters undecided ahead of Brexit vote, poll shows

Those voters who want the UK to 'remain' inside the European Union continue to outnumber the backers of the option to 'leave' but an increasing proportion of voters say they are undecided, an exclusive poll for The Sun by ComRes revealed.

Since March the proportion of voters who said they were 'undecided' about whether to vote for Britain to stay or leave the EU at the 23 June poll had increased by six percentage points, the survey revealed.

The 'remain' camp's seven percentage point lead remained intact, with 45% of respondents saying they would back the UK's continued membership of the EU versus 38% who said they would do the opposite.

In March, 48.0% had said they would vote to 'remain' compared to the 41.0% who backed 'leave'.

However, a total of 38.0% of those polled said they might yet change their mind.

A large minority - 47.0% - said the economy was the main issue in the vote.

An overwhelming 85.0% of Britons recognised it was an "important moment in the history of the UK”, although 36.0% admitted they were already bored by the referendum, compared to the 22.0% who said they were excited by it.
