A housewife owed almost £453 million following a London divorce court battle with her Russian billionaire ex-husband is fighting to stop a yacht worth more than £300 million sailing away.

Tatiana Akhmedova, who is in her 40s, was awarded a 41.5% share of businessman Farkhad Akhmedov's £1 billion-plus fortune by judge in late 2016.

She says Mr Akhmedov, who is in his 60s, has yet to hand over the vast majority of the £453 million Mr Justice Haddon-Cave, who analysed the case at a trial in the Family Division of the High Court in London, said she should get.

Last year, Mr Justice Haddon-Cave ruled that Mr Akhmedov's £346 million yacht - the MV Luna which is currently in Dubai - should be transferred into Ms Akhmedova's name.

Ms Akhmedova's lawyers on Tuesday took legal action in a bid to ensure that the Luna stays where it is.

They persuaded another judge, Mrs Justice Gwynneth Knowles, to make an order aimed at preventing the yacht being sailed away.

Lawyers said they were worried that the Luna might be moved from Dubai to a part of the world where it would be harder for them to enforce orders made by judges in England.
