Hillary Clinton has begun drawing up a battle plan for how to defeat Donald Trump in a general election, which will include unleashing her husband and President Barack Obama as attack dogs.
As she seeks to become the first female US president Mrs Clinton will portray Mr Trump as a misogynist with a temper who ruthlessly preyed on the working class to make his billions.
For months her advisers ignored the property mogul’s political rise, regarding it as an amusing sideshow and watching gleefully as the Republican Party tore itself apart, but now they believe he is their likeliest opponent in November.
During the race for the Democratic nomination Bill Clinton was asked by his wife’s team not to attack her rival Bernie Sanders, but he will go after Mr Trump relentlessly in stump speeches across the country.
Mr Obama has also made clear he is eager to attack Mr Trump as not up to the job of president.
