On 25 May Ireland will vote on whether to loosen restrictions on abortion. It would be a major change in a country that has some of the strictest abortion laws in the Western world. But along with the referendum to change the country’s constitution has come worries about outside interference with the process. Foreign groups have paid for social media advertisements, and in response both Facebook and Google have taken steps to limit such ads – in Google’s case, they’ve banned referendum-related advertising altogether. We hear from both sides of the abortion debate and talk to one group that’s trying to make political advertising more transparent.
