Executives from some of the world’s biggest investment firms have said that they are “optimistic” about Britain’s prospects, in a letter published by The Times ahead of today’s International Investment Summit in London.

Goldman Sachs (GS) CEO David Solomon, Bank of America (BAC) president of international Bernard Mensah, JPMorgan (JPM) global banking co-head Filippo Gori, Legal & General (LGEN.L) CEO António Simões and Aviva (AV.L) CEO Amanda Blanc were among those signatories on the letter.

“As global investors, we believe that there is a very real opportunity for the UK to grow its economy by attracting international investment,” the letter said.

“Britain’s educational establishments, legal system, financial services sector and language form the bedrock of a strong investment proposition. Technological developments, advances in the energy system and greater freedom in capital flows have further enhanced Britain’s position.

“With greater stability, its attractiveness is increased even further. We are optimistic about the future of the economy, and believe it is time to invest in Britain.”
