BRUSSELS - European Union leaders will decide this fall where to move EU banking and medical agencies that they are pulling out of London due to Brexit, using a voting system some liken to the Eurovision song contest.

Most of the remaining 27 EU states have expressed interest in hosting the European Banking Authority and the European Medicines Agency, which together employ more than 1,000 people.

They are keen not to let the historically divisive issue of hosting agencies break their unity over Brexit, although several officials joked about how the choice will be made after leaders agreed at a meeting on Thursday it was the best way to stop arguments.
