While I've no problem with leaflets in multiple languages being done, as it's generally been the norm, particularly in the NHS. They should still be making the effort to speak English, as should anyone that goes to live in another country.
I just think it makes sense, like you say they do it for local councils, NHS, Post offices and most public services. I doesn't necessarily mean that people aren't trying to learn English, just that for important issues that affect people's day to day lives, it's good to communicate in a language that people understand.
Reform are just crying about it because they didn't think to do it themselves
