Donald Trump plans to blame sexual assault allegations against him by a string of women on a conspiracy led by a Mexican billionaire.

The Donald denounced the New York Times as a "weapon" of Hillary Clinton over its "lies" last night, after it published testimony by two women who said he touched them inappropriately.

Trump angrily denied the claims, saying he would address them "in an appropriate way and at an appropriate time, very soon."

According to the Wall Street Journal, that time could be today - and his claims are nothing short of astonishing.

He's understood to be preparing a statement claiming Mexican Billionaire Carlos Slim - who is a shareholder in the New York Times and is a Clinton Foundation donor - is colluding with the Clinton campaign to dredge up decades old stories to rob him of electoral victory.

The Slim family is the largest individual shareholder in the New York Times and he has given between $250,000 and $500,000 to Clinton's charitable body.

Attacking Slim would allow Trump, a former reality TV star and sometime steak salesman, to attack the New York Times, which he said had to be "rescued" by a "foreigner".

“This is totally false,” Arturo Elias, Mr. Slim’s spokesman told the Journal. “Of course we aren’t interfering in the U.S. election. We aren’t even active in Mexican politics.”

And New York Times publisher Arthur Sulzberger Jr said Mr Slim had never sought to influence what the paper reports.

Hillary Clinton's press spokesperson dismissed the attack as "just another deranged right-wing conspiracy theory from Donald Trump’s increasingly desperate campaign."
