Doom-mongers predicted the eurozone would collapse under the weight of Greek debt and the prospect of losing Britain’s hefty contributions.
However, Mr Bowers has hit back at negative predictions, demanding Europe can look forward to a healthy economic future.
He said: “Firstly, the eurozone – it’s member states have travelled a long way since the dark days of Brexit worries and taken incremental but significant steps to stabilise and improve growth.

Enrico Morando said when Britain eventually leaves the bloc it will not be struck by economic disaster.
He told CNBC: “To be honest with you, I think Brexit is a greater threat to the UK economy than for the economy of the European Union.
