Brexit political turmoil escalates, UK credit rating downgraded

The political and economic fallout from Britain's decision to leave the European Union is continuing to escalate.

Here's my report broadcast on The World Today

Britain's outgoing prime minister David Cameron has once again called for unity after the "leave" vote triggered more turmoil in his Conservative party and the Labour opposition.

European leaders are urging Mr Cameron not to waste time in getting the agreed mechanisms in place to exit the EU as quickly and cleanly as possible.

Global sharemarkets ended sharply weaker and two major ratings agencies downgraded Britain's credit status adding to concerns that the UK might slip into recession.
