Dan Boardman-Weston, chief investment officer at BRI Wealth Management

We would suggest that Mr Bennett build a balanced portfolio that includes lower-risk assets such as cash, wealth preservation investment trusts and some infrastructure and commercial property. 

We like Personal Assets Trust and the Ruffer Investment Company, both of which have very good long-term records: they have returned 50pc and 29pc respectively over the past three years.

We also like the Gravis UK Infrastructure Income fund, which consists mostly of infrastructure investment trusts and has an attractive yield of 4pc. For commercial property exposure we’d suggest looking at LXi Reit and Warehouse Reit.

LXi has a diversified portfolio of properties that it rents out to high-quality tenants on long leases with a strong degree of inflation protection. Warehouse Reit offers very attractive exposure to industrial property in Britain and also yields 4pc.

Turning to funds that invest in stocks, we would recommend the Liontrust Special Situations fund. It invests in British companies such as GlaxoSmithKline and BP as well as smaller, faster-growing companies on London’s junior stock market. If Mr Bennett is comfortable taking on some more risk, he could also look at the Gresham House UK Smaller Companies fund, which has returned 55pc in the past three years.

The Baillie Gifford US Growth trust, the Liontrust Global Dividend fund and the Evenlode Global Income fund are all good options for investing in international stocks. If Mr Bennett would like to include some more adventurous themes in his portfolio, we would recommend the BB Healthcare investment trust and the Regnan Sustainable Water & Waste fund. Healthcare and water are very attractive long-term investment themes that we are confident about in the coming decades.
