The wording of such a famous referendum shouldn't be hard to find if you want to know the wording

Edit: just realised I still had this tab open from checking something for another subthread. It says nothing about a committee https://en.wikipedia.org/wiki/File:2016_EU_Referendum_Ballot...

Edit edit :)

On the same page (https://en.wikipedia.org/wiki/2016_United_Kingdom_European_U...), I found this. Perhaps you're remembering that?

> After internal polls suggested that 85% of the UK population wanted more information about the referendum from the government, a leaflet was sent to every household in the UK. It contained details about why the government believed the UK should remain in the EU. This leaflet was criticised by those wanting to leave as giving the remain side an unfair advantage; it was also described as being inaccurate and a waste of taxpayers' money (it cost £9.3m in total). During the campaign, Nigel Farage suggested that there would be public demand for a second referendum should the result be a remain win closer than 52–48%, because the leaflet meant that the remain side had been permitted to spend more money

A lot of people pushed unsuccessfully for a second referendum after the first one but that was never based on any pre-existing legalities or precedent, it was just an attempt to overturn the first result from people who were upset that theyd lost.
