U.K. Prime Minister Theresa May faces a daunting array of demands from European Union nations when the time comes to negotiate Britain¡¯s relationship with the bloc, an analysis of the 27 other members shows.

The survey ¡ª based on responses from ministries, public comments from government officials and interviews with policymakers ¡ª reveals European leaders are laying down their own red lines as May¡¯s team weighs what it wants to seek in the Brexit talks.

The result is a complex patchwork of priorities ¡ª from fishing to shipping, an insistence on freedom of movement to the sovereignty of Gibraltar ¡ª that may run counter to what the U.K. wants to achieve and that it will have to seek to satisfy if May is to meet her commitment of making a success of Britain¡¯s withdrawal from the EU.
