Ed Miliband has promised to bring the same attack to Britain's pension's system that he brought to News International.
Speaking at a reporters' lunch in parliament, the Labour leader joked about his relationship with Gordon Brown before assuring the assembled journalists that he would be making radical proposals on overhauling the country's pension system.
"There are no hard feelings between me and News International," he said.
"They want me to lose, I want them in jail."
Miliband said that after taking on the media and banking sectors he was turning his attention to pensions, with a focus on high charges and poor returns.
The agenda is likely to appeal to Middle England voters, as Labour tries to steal the voters who switched to the Conservatives in 2010.
While the party was short on detailed plans today, it made it clear the issue would be front and centre of Labour's activities after the summer recess.
Asked about the election in 2015, Miliband said: "The convention breakers will succeed."
The Labour leader was in a self-deprecating mood over lunch, as he repeatedly poked fun at Brown and his own mistakes.
At one point he sarcastically told reporters he learned not to hold "grudges" from Brown.
He then joked of a meeting with Burmese democracy leader Aung San Suu Kyi, where he discussed living under years of oppression, before she said: "Enough about Gordon".
The Labour leader also made light of his tweet upon the death of Bob Holness, when he mistakenly said he worked on 'blackbusters'.
Miliband joked: "I'm just very relieved he never presented Treasure Hunt."
