Grandparents in the UK spend a massive £2,697 on their grandchildren —and £325 of that is on Christmas presents alone, according to research.

A survey of 2,000 people by SunLife Insurance found that the average British grandparent has four grandchildren and is set to spend £81 on each of them, totalling £324. This is more than three times what they will spend on their partner’s Christmas present – about £95 average.
