Vince Cable on way out?

This Business Secretary Vince Cable was recorded by undercover journalists from the Telegraph claiming that he had declared War on the NewsCorp Empire and that if he felt the coalition was moving to far away from his beliefs would use his 'Nuclear Option' and resign from Government and bring the coalition down around him.

By declaring unilateral war on Rupert Murdoch and (kinda)publicly revealing his Nuclear option, he has not only lost the powers he planned to use against Murdoch but also had his Nuclear option disarmed. The accusations have now begun from Labour that Cable has retained his Cabinet position simply to prop up the coalition and keep the Social Democratic wing of the Lib Dems happy.

But why is Vince still on the Cabinet?

Labour's idea that Cable has been retained to keep the Lib Dems happy isn't that far-fetched, He is after all one of the highest profile Lib Dems that their small parliamentary group has. Keeping him, though unpopular, keeps the Lib Dems from being overshadowed by the Tories.

However stripped of his powers to act in the BSkyB takeover has made Vince Cable a bit of a lame duck, his credibility, in using the powers afforded to his position as Business Secretary, is severely damaged. But perhaps Vince is simply being kept on the cabinet to keep the seat warm over the holidays as the Coalition hope to bring David Laws back onto the Coalition frontline.

David Laws is a Lib Dem who resigned from government due to issues with his expenses, however he has managed to avoid the expenses stigma due to the unceremonial reveal of his sexuality as collateral that accompanied his expense account. With a career as an investment banker backing his CV he would be a Prime Candidate to move onto the Business Portfolio.

For Vince Cable, he knows that being asked to leave the Cabinet would be his own fault, but how would he find being pushed to the backbenches with Lib Dems unhappy with the coalition's policies?
