UN General Assembly: Watch live stream as Barack Obama, Theresa May and world leaders make addresses

World leaders including Barack Obama, Theresa May and Justin Trudeau are to address the 71st UN General Assembly today (20 September), the first of two days of annual autumn talks.

The speeches - which will cover a variety of topics - begin at 9am local time in New York (2pm BST). They are split into two halves with the second beginning at 3pm (8pm BST).

Among those leaders speaking to the assembly are French President François Hollande, Canadian Prime Minister Justin Trudeau, Nigerian President Muhammadu Buhari and Turkish President Recep Tayyip Erdoğan.

Obama's speech will be his last to the UN General Assembly as US president. The Associated Press has reported he is expected to reassure foreign leaders that the world is better equipped to tackle its challenges than at almost any point in history despite a cascade of harrowing crises that seem devoid of viable solutions.

Speaking at preliminary summit on refugees and migrants yesterday (19 September), British Prime Minister Theresa May said both MI6 and GCHQ will be given additional resources to break up networks in countries involved in the slave trade.

In her second address she is expected to attempt to allay fears over Britain's June vote to leave the European Union.
