Britain should vote to stay in Europe, even though the attractiveness of remaining within the European Union has diminished sharply over the last 12 months, Ian Bremmer, the leading international political scientist has told The Telegraph.

Despite Europe’s manifest inability to tackle the migrant crisis or, increasingly, uphold its founding values, Mr Bremmer said that Britain still had more to lose than to gain from a “Brexit” which would pose a risk to both British and European stability.

Mr Bremmer, the president of the Eurasia Group risk consultancy and a leading international foreign policy guru, said the risk of Scotland leaving the Union, a sharp fall-off in foreign investment and longer-term damage to London's standing as a global financial capital all weighed against voting to leave.

"There are strong reasons for the Brits to ultimately vote to stay, even in an EU that is rather less attractive and useful for the Brits than it has been over the past decades," he said.

In a wide-ranging interview covering Brexit, Donald Trump and George Osborne's recent attempts to curry favour with China, Mr Bremmer paints a gloomy picture of a world where "values are breaking down", with too many countries – including Britain and the US – putting short-term self interest over the need to invest in long-term global stability.

"We don’t have a strong Europe or a strong United States – you are going to be living in a world that is looking a lot more like the model that the Chinese and Russians are putting out there," he said.
