Hello! Here's what you need to know on Tuesday.

1. Turkish Nobel Prize winner: Turkey is sliding into a "reign of terror." "Freedom of thought no longer exists. We are distancing ourselves at high speed from a state of law and heading towards a regime of terror," Nobel-winning Turkish writer Orhan Pamuk said.

2. Brexit will cost Britain £43.8 billion over the next 3 years. The British Chamber of Commerce has drastically cut growth forecasts for Britain's economy in the wake of Brexit.

3. The BBC lost 'The Great British Bake Off' to Channel 4. The BBC failed to agree a new contract for the show - and rival Channel 4 swooped.

5. North Korea's fifth and largest nuclear test last Friday was a wake-up call to us all. "The tone among Korea watchers has changed. It's not funny anymore..." Thomas Karako, director of the Missile Defense Project at the Center for Strategic and International Studies, told Business Insider.

6. 1 ISIS recruiter has emerged as the link between 4 different plots to attack France.
