London - It is the time of year when festive spending can quickly spiral out of control.
And experts warn this could lead to "financial infidelity" – couples hiding their spending and debts from each other.
More than a third of people in relationships are lying about their finances, a study has found. This can range from buying an expensive daily latte when they are supposed to be saving for a holiday, to hiding credit card bills or squirrelling away money in a secret savings account.
Researchers from four universities, including University College London, looked at a survey of more than 12 000 bank customers across 13 countries, including the UK.
They found almost 36 percent were engaging in at least one type of "financial infidelity" – managing money in a way their partner might disapprove of, and hiding the evidence.
