Dame Julia Hoggett says negative sentiment about the UK market has pushed companies to leave in the past
The UK needs to do more back its own companies at a time when a growing number are choosing to list their shares in the US rather than at home, the boss of the London Stock Exchange (LSE) has told the BBC.
Dame Julia Hoggett said the government needed to make it "more attractive" to invest in the UK stock market, otherwise big firms would continue to look overseas for their next stage of growth.
Over the last few years, scores of big firms have left the London market, are considering a move or have been bought by private foreign investors.
The fear is this weakens the UK economy by reducing tax revenues and depressing business valuations.
