Catalonia goes to the polls on Sunday, May 28, with voters in almost 1,000 municipalities set to choose the new makeup of their city and town councils and ultimately their new mayor.

Cristina Tomàs White and Guifré Jordan join Lorcan Doherty to look at some of the most hotly contested council battles, including an unprecedented four-horse race for mayor in Barcelona.

This week's Catalan phrase is "estar com gat i gos," which means "to fight like cats and dogs."
