Insurance Times' circulation grows by the day and, given the following evidence, has now reached Nigeria.

Backchat wrote in March of the traditional money-laundering letter received by Maidstone brokers Jewell Insurance Agencies. It offered 25% off a £37.5m fund for a £5,000 donation and the use of a UK bank account.

Word that Marion Jewell had spoken to the press about the clandestine operation obviously reached Dr Peter Oke, director of project implementation at the Nigeria National Petroleum Corporation.

In his second letter to the broker, Dr Oke upped Jewell's cut off the £37.5m from 25% to 30%, but warned her that it must be kept "top secret, because of the nature of this business".
