Germany needs a "comprehensive" new trade EU deal with the UK after Brexit to minimise the potential fallout for its own economy, a leading politician has warned.

Ilse Aigner, the Bavarian economy minister, said that Brexit poses a "high risk" to the economy and argued that the UK is one of the "most important trading partners for Bavaria", one of Germany's most prosperous states.

Britain is hoping that Germany will help to temper demands from France that Britain must "pay a price" for its decision to leave the EU.
