Labour Leader Ed Miliband, Former Prime Minister Sir John Major, and Labour's Deputy Leader Harriet Harman are all expected to give evidence to the Leveson Inquiry on Tuesday.
Chancellor George Osborne has told the Leveson Inquiry there was no "vast conspiracy" to hand control of BSkyB to Rupert Murdoch.
George Osborne is quizzed on News Corporation's take-over of BSkyB. But the questions on Andy Coulson's appointment are still to come.
The former Prime Minister's evidence to the Leveson Inquiry has revealed how he felt 'unfairly characterised'.
