Where is Jersey? Location of the Channel island, map - and is it part of the UK or France

Jersey is certainly an interesting place, but what is the history of the island, and why has it been in the news lately?

Royal Navy ships are patrolling the waters around Jersey amid an ongoing row between the island and France over post-Brexit fishing rights.

HMS Severn and HMS Tamar have been deployed by the UK Government to “monitor the situation”, and Agence France-Presse reports France has dispatched two patrol vessels as dozens of French fishing boats gathered near the island.
