US President Barack Obama has said the UK vote to leave the EU raises "long term concerns about global growth".
He said the result of the referendum would freeze the possibilities of investment in Great Britain or in Europe as a whole.
Meanwhile as the fallout continues in Britain
Theresa May and Boris Johnson will enter the race to become the next Prime Minister later.
The two Tory heavyweights are expected to say they've got the ability to unite the party after the departure of David Cameron.
Meanwhile the Labour leader Jeremy Corbyn appears to be holding onto his job, for now.
A statement from 10 of the party's general secretaries says he should only be challenged by the proper democratic procedures.
80 per cent of Labour members said they had no confidence in Mr Corbyn after the Brexit result.
