Boris Johnson is trusted to tell the truth about Europe by twice as many voters as trust David Cameron, according to a ComRes poll for The Independent. By a two-to-one margin, 45 per cent to 21 per cent, voters say that Mr Johnson is “more likely to tell the truth about the EU” than Mr Cameron.

By a smaller margin, 39 per cent to 24 per cent, campaigners for Leave generally are considered “more likely to tell the truth” than campaigners for Remain.

THE REFERENDUM CAMPAIGNS

Following key speeches this week, Britons are more than twice as likely to say Boris Johnson would tell the truth about the EU than David Cameron (45% v 21%).

Conservative voters also say Boris Johnson is more likely to tell the truth about the EU than the Prime Minister (42% v 27%).

Similarly, Britons tend to say the campaigners for leaving the EU are more likely to tell the truth than the remain campaigners (39% v 24%), although a significant minority say they don’t know (38%).

THE EU REFERENDUM

The British public remain divided over whether they would be personally better off if Britain left the EU or remained part of it (29% v 33%). Around two in five (38%) say they don’t know how the referendum outcome would personally affect them.

There has been a rise in the proportion of Britons saying national security would be better if Britain left the EU - 42% say it would be stronger if Britain left, compared to 38% who say it would be stronger if Britain remained. This represents an increase of 7 points from March in favour of leaving (35% in March 2016).

However, attitudes towards immigration are clear; British adults are more than twice as likely to say the government could control Britain’s borders better if it left the EU (57% v 27% if Britain remains).

PUBLIC KNOWLEDGE OF THE EU

There are mixed levels of knowledge about the EU among the British public.

For example, around four in five adults (78%) correctly say the UK pays more into the EU budget than it gets back. However, three in five (61%) British adults falsely believe most British laws have to be approved by the European Parliament.

There are no differences between supporters of the two main parties, with similar proportions of both Conservative and Labour voters selecting the same option for each statement. However, Conservative voters are more likely than Labour voters to believe that most British laws have to be approved by the European Parliament, despite this not being the case (64% Conservatives v 52% Labour).

Conservative voters remain split on whether they would benefit personally if Britain left the EU (29% v 33% remain).

Following Jeremy Corbyn’s speech this week on the importance of young voters in the referendum, 18-24 year olds are most likely to say they would be personally better off if Britain remained in the EU (55% v 20% leave).

o Older voters aged 65+ are the opposite and are more likely to say they would be personally better off if Britain left the EU than remained (34% v 18%).

Option 1 % % Option 2 Don’t Know The British government could control Britain’s borders better if it left the EU 57% 27% The British government can control Britain’s borders better by staying in the EU 16% Britain’s national security would be stronger if Britain left the EU 42% (+7) 38% (-4) Britain’s national security is stronger by staying in the EU 19% (-4)

Labour voters are split over whether the government could control Britain’s borders better if it left or stays in the EU (44% v 40%).

Conservative voters are almost twice as likely to believe the leave campaigners are more likely to tell the truth about the EU than the remain camp (41% v 22%). Labour voters are more divided but lean towards the remain camp (35% believe remain are more likely to tell the truth v 29% leave).

Public knowledge of the EU

Q: Please indicate whether you think each of the following statements about the EU is true or false?

Option TRUE FALSE The UK pays more into the EU budget than it gets back 78% 22% There are 29 countries in the European Union 73% 27% UK citizens need a passport to get into another EU country 71% 29% The European Parliament meets 12 times a year in Strasbourg and the rest of the year in Brussels 66% 34% Most British laws have to be approved by the European Parliament 61% 39% The Treasury estimates that if Britain leaves the EU it would cost the average household £4,300 a year by 2030 60% 40% The EU has an official anthem 30% 70% The EU is responsible for setting taxes in Britain 20% 80% The EU has an official army 14% 86%

Base: GB adults (n=2,043). Statements in green are true, statements in red are false.

Three in five (60%) Britons correctly identify that the Treasury estimates that if Britain left the EU, it would cost the average household £4,300 a year by 2020.

British adults are unaware of the administrative side of the EU; around three quarters (73%) falsely believe there are 29 countries in the European Union. In addition, seven in ten (70%) are unaware the EU has an official anthem (which is of course, ‘Ode to Joy’).

UKIP voters are far more likely than voters from other parties to say most British laws have to be approved by the European Parliament (80%), despite this not being the case. UKIP voters are also the only group with a majority selecting ‘false’ when asked about the Treasury estimation that Brexit would cost the average household £4,300 a year by 2030 (61% false v 39% true).
