TV presenters Eamonn Holmes and Ruth Langsford are heading for a High Court showdown over their estimated 10 million pound divorce settlement after peace talks collapsed.

The case, listed as Ruth Holmes versus Eamonn Holmes, has already had two hearings, with a full trial expected in November. What was once one of British television's most enduring partnerships is now being unpicked in open court, with the couple's finances laid bare for public scrutiny.

Issues at trial could include a fortune of around 5 million pounds and the couple's six-bedroom home in Weybridge, which was bought for 3.6 million pounds. The property, like much of the couple's wealth, was accumulated over decades at the top of daytime television, where the pair were among the highest-paid presenters in the country.

Holmes and Langsford presented together for years, becoming one of the most recognisable couples on British TV. Their on-screen chemistry made them favourites with viewers, and their split has been followed closely by a public that felt it knew them. The collapse of settlement talks means the details of their financial lives will now be examined in detail by a judge, a prospect neither side will relish.

High-value divorce cases often turn on questions of contribution, need and the division of assets built up during a marriage. With 10 million pounds at stake, both sides are expected to fight hard over every element of the settlement, from property and pensions to the value of future earnings. The two preliminary hearings suggest the legal teams are already deeply entrenched.

The November trial is likely to attract intense media attention, with every revelation pored over by the press. For two presenters who made their names in the glare of the studio lights, the final act of their marriage will play out in the very different glare of the courtroom, and the outcome will set the financial terms on which they finally go their separate ways.

The couple's split was announced to widespread sadness among viewers who had watched them together for decades. Both have continued working, but the divorce proceedings have cast a shadow over their public appearances. Legal experts say high-profile cases like this one often settle before trial, as the prospect of intimate financial details becoming public concentrates minds. But with two hearings already behind them and positions apparently entrenched, there is no guarantee of a last-minute deal. The November trial date now looms as the moment when the financial affairs of one of television's most famous couples will be laid bare.
