According to the same survey, only 9% of respondents currently think that leaving the EU has been a success, according to EU Helpers.
In addition, even though 30% of respondents, or less than one-third, agreed, the remaining participants in this study are doubtful that the policy will ultimately be successful.
In a fictitious referendum on Britain's re-admission to the bloc, 48% would vote in favor of it, 32% would vote against it, and the remaining 14% would cast an undecided ballot.
Despite the larger percentage of respondents who favor the UK rejoining the EU, the authors have advised caution when interpreting the findings.
They contend that the nearly universal disapproval of the program does not necessarily indicate a vote in favor of re-entering the EU.
Anand Menon, the head of UKICE, claimed that the findings revealed the limitations on the Brexit proposals of both the Labour and Conservative party leaders.
The researcher at UKICE, Sophie Stowers, stressed that this data disproves many common misconceptions about Leave voters who are dissatisfied with the direction of Brexit.
Since the UK formally left the EU, the residents of both areas have been subject to various restrictions, which has added to their challenges.
Another study conducted in August of this year found that over half of British musicians and music industry workers felt that Brexit had reduced their opportunities to work in the EU.
Britons have found it difficult to go to the EU, particularly during this busy summer period. According to data from the HM Passport Office, 254,316 vacationers' valid passports do not comply with the post-Brexit regulations for entering the EU.
According to the statistics, a quarter of a million travelers with valid passports may encounter additional challenges this summer as a result of EU regulations.
An increase in the number of Britons regretting their vote to leave the EU was found in a recent YouGov survey. The same revealed that 55% of respondents who took part in this poll would vote to stay in the EU, while 31% would vote to leave.
