Opportunities for Policy Research for postgrads

Hi guys. Was just wondering if anyone had suggestions for internship/ entry level research fellowships in the UK for an MSc graduate of sociology and politics and climate change. I’m applying for the fairly well known organisations like the IfG, CER, Chatham House etc etc, but I don’t think I have a CV that can compete with a lot of the applicants for there opps. For context I went to a post-92 uni for undergrad and studied literature and I’m now at a high ranking uni for masters with a deferred PhD place. Have had a little experience in policy analysis through an internship at undergrad, but nothing which would classify me as ‘experienced’ in the field outside of academia.

Any tips would be greatly appreciated :)
