The CFP has not ended maritime clashes between the UK and other countries, both in the EU and in the EU. In 1993, French fishermen collided with the Royal Navy because of their rights in waters near the Channel Islands.  In 2010, the “mackerel war” erupted after Iceland and fists changed their minds about the quotas of these previously agreed fish in their waters, where stocks had been displaced in response to climate change, greatly increasing the proportion they allowed themselves to make of their ECZs; Subsequently, Scottish trawlers blocked a ship landing 1,100 tonnes (1,100 tonnes long; 1,200 short tons) of mackerel to a processing plant in Peterhead.  Two years later, French ships began the “Scallop War” and threw stones at British diggers who took these crustaceans out into the English Channel flowerbeds, which the French claimed were within 22 km [d] of their shores, and therefore not for the British.  At the end of November, at the end of November, when the deadline for reaching an agreement expired, the ESMA announced that all trading in euro-denominated derivatives was to take place either within the EU or in a market equivalent to that of the United States, Australia or Hong Kong from the beginning of 2021. Given that London has become the most popular derivatives market in the world, the EU considered it a “hardball” step, as the parties to the transaction must decide to trade in the UK or THE EU and fragment liquidity, provided trading is possible. “[D] his is the EU telling the UK – it`s their mess, they can solve it,” said a lawyer from Ashurst who complies with the regulations.  In Scotland, a country more dependent on their industry than England, the fisherman was furious at competition from Dutch ships in the country`s waters, and when their King James assembled the Scottish and English crowns in 1609 as Jacob I, he reversed the tolerant policy of his predecessors with regard to foreign fishing in British coastal waters and demanded a high royalty. Dutch jurist Hugo Grotius had also argued in favour of the “Mare Liberum” principle in response to the clashes between his country and Portugal, according to which the seas are a common property and that all nations and all citizens have the right to use it after authorization. In 1635, John Selden of England responded with the principle of the Closed Sea Pond Clausum, according to which a nation could appropriate the seas as easily as it would land.  The withdrawal agreement by which the United Kingdom left the European Union at the end of January 2020 contained a non-binding political declaration, concluded last October, setting out the terms of post-Brexit relations, with the aim of reaching a comprehensive trade agreement by the end of 2020.
