Supreme Court judges have "reluctantly" forced a woman to stay in an unhappy marriage as they urged Parliament to change the law on divorce.

The unanimous decision by five senior judges means Tini Owens, 68, must remain married to husband Hugh, 80, until at least 2020 because she has been unable to show sufficiently good grounds for the proposed split.

Judges said the case "generates uneasy feelings" and suggested that the current system, in which partners must demonstrate bad behaviour by their spouse, was out of date.

Mrs Owens first approached lawyers about a divorce in 2012, before moving out and filing her petition in 2015. Mr Owens has repeatedly argued that their marriage has not broken down and refused to consent to the divorce.

She will now have to wait until 2020, when the couple will have lived apart for five years, in order to divorce him.
