What significant factor does 'Brexit means Brexit' encapsulate?

The phrase 'Brexit means Brexit' encapsulates the commitment to leave the European Union (EU). It was used to convey a definitive stance on the outcome of the Brexit referendum, emphasizing that the government's focus was on fulfilling the mandate given by the voters. This statement aimed to reinforce the message that the United Kingdom would not be reconsidering its decision to exit the EU or reversing the process.

In the context of Brexit, this phrase served as a rallying point for those who supported leaving the EU, indicating that the government would proceed with the separation and seek to implement the necessary changes associated with that exit. The emphasis was on taking action to follow through on the decision made in the referendum rather than continuing to negotiate terms or suggesting any desire to maintain aspects of EU membership.
