Interesting article about the brexit negotiations:
Britain has a secret weapon in its Brexit negotiations: America's spies

The UK-US special relationship is the first element here. As the sole European member of the "Five Eyes" intelligence alliance, Britain has access to U.S. intelligence material that other European nations do not.
When it comes to negotiations with the EU, the NSA and GCHQ will have another important role: spying on EU negotiators. The NSA is likely to do this so as to give US policymakers early notice of how the negotiations are progressing (Edward Snowden’s leaks showed a clear US intelligence interest in intra-EU discussions). But the US is also likely to share much of what it learns with the UK. President Trump genuinely seems to like May and dislike Angela Merkel and the EU. Whether it’s the US intelligence community, the British intelligence community, or a joint operation, the UK and US are masters of spying against protected targets. European leaders know this.
