My mum and dad are planning on visiting my sister in the UK. My dad is an EU citizen but my mom is not. She does have a residence permit in Italy though (I think it's called permesso di soggiorno).
I've read about EU citizens being able to travel with their non-EU spouses if they have an article 10 residence permit (see link below) so I wanted to ask if her residence card qualifies as an article 10 permit and if she can travel with my dad without having to apply for a visa?
