A quarter of married British women are hitched to younger men and this ONE Life special (BBC One’s social documentary strand) sets out on a journey to discover who these people are and what’s brought them together. For older, successful women it seems an obvious choice to have a younger trophy boyfriend in his sexual prime, but what’s in it for the younger men? Are they just looking for a temporary Sugar Mummy, or are they looking for love? How often do these relationships sustain and end in marriage? Are there older husbands out there who have been dumped by their wives for a younger version? How many women over 60 are out there dating or married to men in their 20s or 30s? What is the biggest gap?
