LONDON, Jan 17 (Reuters) - Private equity firm TPG

and Russian state-owned firms Rosatom and Transneft

on Friday won their bid to block jailed tycoon

Ziyavudin Magomedov's $14 billion London lawsuit over an alleged

conspiracy to strip his assets.

Magomedov sued the companies and several others at London's

High Court, alleging his 2018 arrest on embezzlement charges

prompted a Russian state-supported scheme to strip him of his

holdings in valuable port operators.

The defendants all denied the allegations and last year

argued that the lawsuit should be thrown out, with TPG's lawyers

accusing Magomedov of concocting "preposterous allegations".

Judge Robert Bright ruled that the case should not continue,

saying in a written ruling that there was "no serious issue to

be tried" against TPG or Transneft and that any case against

Rosatom should be heard in Cyprus.
