*Plus* at the ICM.

The International Congress of Mathematicians (ICM) is set to begin today, August 1 2018, in Rio de Janeiro, Brazil. Over the next nine days thousands of mathematicians from all over the world will share their work and also honour some of the best talent in the field. The ICM sees the award of the Fields medals, awarded every four years to up to four mathematicians under the age of 40 and regarded one of the highest honour in mathematics, as well as a range of other highly regarded prizes.

*Plus* has reported on the last two ICMs (in India and South Korea) and we are very pleased to be present at this one too. Over the next ten days we will bring you up to date news from the congress, starting with the announcement of the prize winners tomorrow. We are very grateful for the generous support of the London Mathematical Society and the Institute of Mathematics and its Applications.
