A new Brexit poll has given a very narrow lead to the 'leave' campaign

A new poll shows that the campaign for Britain to pull out of the EU is currently in the lead - but only just.

The research, put together by Future Thinking, says 33% of respondents plan to vote to leave the 28-member union on June 23rd, compared to 32% who want Britain to remain.

This latest set of results is encouraging news for 'leave' campaigners who just a few weeks ago were falling behind across number of opinion polls, as seen in the chart below.

With less than four months to go until Britain's fate is decided, the amount of voters who are yet to make up their mind is a sizable 29%.

The results illustrate a clear difference in opinion between the generations.

Almost 47% of 18-24 year olds want Britain to remain in the EU compared to just 12% who want to pull out, while 44% of people aged 65 and above will vote for the country to leave compared to 29% who'll vote to remain.

Interestingly, the will to leave the union is significantly stronger among men.

The survey, based on responses from 10,000 people, says that 42% of men plan to vote for a Brexit, compared to 28% of women who plan to do the same.

With the battle lines drawn, the Brexit debate has hotted up in recent days with strong words being exchanged between the two sides.

Tory minister Iain Duncan Smith last week accused Prime Minister David Cameron of having a "low opinion" of British people, while Labour politician and think tank-head Peter Mandelson said Brexit campaigners are selling a "fantasy" to British people.
