Wikipedia:Articles for deletion/List of supermarket chains in Portugal
I count 2 reliable sources at the bottom of the article. According to , "the phrase "original research" is used on Wikipedia to refer to material for which no reliable, published sources exist". So the nominator's basis for deletion is incorrect. There are also loads of reliable sources that discuss the distribution chains' market in Portugal, mainly https://www.ine.pt/xportal/xmain?xpid=INE&xpgid=ine_publicacoes&PUBLICACOESpub_boui=358631574&PUBLICACOESmodo=2 the National Institute of Statistics, that compiles that information https://www.ine.pt/xportal/xmain?xpgid=ine_tema&xpid=INE&tema_cod=1710&xlang=pt in quite a detailed way, and https://jornaleconomico.sapo.pt/noticias/pingo-doce-vai-abrir-mais-10-lojas-em-2019-417045 Economy-focused newspapers / https://www.distribuicaohoje.com/retalho/lidl-ja-tem-255-lojas-em-portugal/ retail-focused news, but also https://www.publico.pt/2017/01/23/economia/noticia/pingo-doce-e-continente-alcancam-as-maiores-vendas-desde-2010-1759073 mainstream newspapers, beyond what's already in the article. (By the way, did the nominator perform a  search in Portuguese? The above are just examples) The article List of supermarket chains in the United Kingdom is an example of how the Portuguese article can be improved
