The provided news articles focus on Maria Eugènia Gay, a Barcelona city councilor responsible for international relations and head of District 11, which manages partnerships with Palestinian cities affected by the Israeli army. She also serves as the councilor for Sarrià-Sant Gervasi, focusing on local governance. One article highlights her work in Sarrià-Sant Gervasi, where she aims to add 200 public housing units in three years. The other article discusses the reappearance of a plaque commemorating Vicenç Albert Ballester, the creator of the Catalan estelada flag, which went missing in 2018 after the demolition of old courthouses. The plaque was found for sale on Wallapop and acquired by a member of VexiBand. Neither article mentions anyone named Collboni, so it's impossible to provide information about them based on the given context.
