Unite accused of 'intimidation' tactics over Grangemouth
Members of the Unite union involved in the bitter dispute at Grangemouth have been accused of trying to intimidate company bosses and their families.
In one case, Unite members congregated outside the home of a company director with an inflatable rat.
David Cameron said: "No one has a right to intimidate, nobody has a right to bully, nobody has a right to threaten people's families, no one has a right to threaten people in their homes, and if these things have happened, it is very serious - it needs to be properly examined."
The union insists all its campaigning activities have been legal.
