Cabinet reshuffle: What happened and why?

It wasn't supposed to end like this. Or was it? Sajid Javid's shock resignation as Chancellor was the main focus of the Cabinet reshuffle but what happened and why?Adam Boulton and guests dissect the behind-closed-doors discussions which resulted in the Prime Minister having much more sway over his new Chancellor's economic plans.They also assess the reasoning behind the sacking of the popular Northern Ireland Secretary Julian Smith, whether Sinn Fein's gain in last week's election in the Republic of Ireland increases the chances of a referendum on unification and try to solve the conundrum of who DID pay for the PM's new year holiday.Joining Adam this week are the comment and features Editor of City AM Rachel Cunliffe, the writer and author of 'Who's Afraid of the Easter Rising' and 'The European Union and the End of Politics' James Heartfield, Sky's political correspondent Tamara Cohen and Sky's senior Ireland correspondent David Blevins.
