Was Crocodile stronger at Marineford? Or was he holding back in Alabasta?

 During the Alabasta arc, Crocodile displayed a level of power that was initially considered overwhelming by the Straw Hat Pirates. He possessed the Logia-type Devil Fruit called the Suna Suna no Mi (Sand-Sand Fruit), which granted him the ability to control and transform into sand. He had a reputation as a Shichibukai and controlled the desert kingdom of Alabasta from the shadows. His strength was showcased through his battles with Luffy and others. At Marineford, Crocodile was present as part of the war that took place at Marine Headquarters. While he did participate in the battle, he didn't display the same level of dominance as some other powerful characters present. This has led fans to speculate that he might not have been as strong as initially portrayed in Alabasta. It's important to note that power scaling and character abilities can be subject to interpretation and development by the author. Oda often keeps details deliberately open-ended to keep the story intriguing.

Does the UK government have a plan for Brexit?

 The United Kingdom (UK) officially left the European Union (EU) on January 31, 2020, and entered a transition period that ended on December 31, 2020. During the transition period, the UK and the EU negotiated the terms of their future relationship, including trade and other areas of cooperation.

As of January 1, 2021, the UK is no longer a member of the EU and is considered a "third country" by the EU. The UK and the EU have agreed on a trade and cooperation agreement that establishes the terms of their future relationship, including provisions on trade in goods and services, and cooperation in areas such as security and law enforcement, transport, energy, and the environment.

The UK government has outlined its plan for the post-Brexit relationship with the EU in a series of documents, including the "Political Declaration" that was agreed upon by the UK and the EU in October 2019, and the UK-EU Trade and Cooperation Agreement that was signed on December 24, 2020.

In summary, the UK government's plan for Brexit involves establishing a new, independent trade policy and negotiating trade agreements with countries around the world, while also seeking to cooperate with the EU in areas such as security, law enforcement, and the environment. The UK will no longer be subject to the jurisdiction of the EU's institutions and will be able to set its own laws and regulations. However, the UK will also have to adhere to certain rules and standards in order to access the EU's single market for goods and services.
