[5] The coalition was formed in order to participate in the 2019 European elections, joining several formations from the Portuguese political right.

The plans for the coalition started in March 2019 when the Chega party was not approved at the Constitutional Court of Portugal.

On 1 April 2019, the parties asked for the first time to the Constitutional Court to run together in a single list under the name Chega (another way of saying "Enough", synonym for Basta).

A slightly different name was put forward, Coligação Chega ("Enough Coalition"), but it was also refused for the same reason.

[9] On 12 April, Ventura admitted he would no longer be the leader of the coalition if it was rejected one more time by the Constitutional Court.
