Members of Bremain in Spain want people living on the costas to throw pro-Brexit placards and memorabilia into fires lit to celebrate Fiesta de San Juan on June 23.
The date also marks the first anniversary of the British referendum on EU membership.
Sue Wilson, group spokeswoman, hopes participation in the event will remind UK politicians of expats’ opposition to Brexit, while showing Spaniards their wish to integrate into Spanish life.
“Our plan is to get as many people together,with placards with slogans like “strong and stable leadership’ and ‘Brexit means Brexit.’
“Most importantly, take loads of photos for us to use on our website and in press releases across UK and Spain.”
