In the wake of the pensions freedoms which came into force in April he claims that the baby boomer generation tend to rely too heavily on property investments.
Williams said: “The current generation of pensioners has always had an obsession with property, despite the fact that the market is notoriously volatile.
“Those looking to invest their pension in this way should be warned that bricks and mortar cannot, and should not, be the sole answer to how they fund their retirement.
“The key for investors is to diversify their exposure and make sure they are not leaving themselves vulnerable by taking too much risk on any one market.”
