An invitation to tender for the huge reinsurance programme, which enables the leading protection and indemnity clubs to offer $3bn of cover, has produced what may appear to be just a tweaking of arrangements.

Miller Insurance Services, the unchallenged broker of the programme for the past 65 years, retains the core contract, with Aon Benfield named as co-broker.

Miller was previously the broker of the collective excess-of-loss reinsurance programme bought by the 13 International Group clubs.
