Which long-term investment would you most trust with your money?

Property has long been Britain's favourite wealth-builder, though stamp duty, mortgage rates and Section 24 have made it less of a sure thing.

A flexible way to invest up to £20,000 a year tax-free, usually via index funds tracking the FTSE or global markets.

Long-term, locked away until 57, but the tax relief and employer contributions are hard to beat for retirement planning.

Government-backed and capital-secure, with the chance of a tax-free win each month instead of guaranteed interest.

A traditional store of value that holds its own when currencies wobble, but it pays no income and storage isn't free.
