'Stop throwing shade' - the woman trying to stop firms leaving the UK

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.

"If we want Britain to back Britain, which is what I hear the chancellor and the prime minister saying, then let's make sure that we're creating structural incentives to do so," Dame Julia told the BBC's Big Boss podcast.

The LSE's main market is made up of around 930 companies with a total market value of about £4.9 trillion.

But in the last few years, many firms have delisted or moved away from the LSE, including takeaway chain Just Eat, which joined the Amsterdam stock exchange, travel giant Tui which opted for Frankfurt, and Paddy Power-owner Flutter which now trades in New York.

Meanwhile, the number of companies newly listing their shares in London has dwindled.

Last year, there were 23 initial public offerings (IPOs) on the London market, with £2.1bn raised. In the US, which has much larger capital markets, there were 354 with $44bn (£33bn) raised.

It has coincided in a big rise of UK investment money flowing into US stocks in search of better returns.

"We talk as a nation about wanting growth in every postcode, but at the moment, a lot of us are funding growth in every zip code," Dame Julia said.

There was "no shortage of great companies and no shortage of capital", she added.
