"Business for New Europe (BNE) said a vote to quit the EU could force some companies that use Britain as a European base to leave the UK. The group warned that businesses will hold back on investment in Britain because of the uncertainty created by the prospect of the referendum.
Business leaders on BNE’s advisory council include Sir Michael Rake, the chairman of BT, Chris Gibson-Smith, the chairman of the London Stock Exchange, and Sir Philip Hampton, the chairman of Royal Bank of Scotland. BNE is non-partisan and campaigns for Britain to stay in a less bureaucratic EU."
The chairman of the London Stock Exchange should carry some weight.
