Spanish Prime Minister Pedro Sanchez has called on workers in the public and private sectors to stop wearing ties, as an energy-saving measure in the heat.
About:
Mr Sanchez said, his government will adopt urgent energy-saving measures on as European countries strive to become less dependent on Russian gas in the wake of the war in Ukraine.
Over the past few weeks, Europe has experienced record-high temperatures.
Prime Minister Sanchez said, not wearing ties will ensure people stay cooler and therefore lower energy costs because air conditioners will be used less often.
Spain is not the first to take this move. In 2011, Japan introduced its "Super Cool Biz" campaign, which encouraged office workers to wear cooler clothes in summer.
And during sweltering temperatures in the UK recently, politicians were told they could ditch their suit jackets while in the House of Commons.
