The FCA has told firms to do more to ensure politicians, senior public servants and their families are not treated unfairly.

The soaring cost of regulation came home with a thump with a report this week from the FCA that its average salary is now over £71,000 a year - more than double the mean UK average.

The average salary at the FCA has risen by an average of 4.8% this year to £71,290, with some younger staff members receiving an 11.2% increase.

The FCA has published rules for a simplified listings regime in its biggest shake-up in over three decades to support a wider range of financial services firms to issue their shares on a UK exchange.
