Justice Minister Christoph Blocher risks leaving the Swiss cabinet the way he entered it four years ago – with a bang.
His election on December 10, 2003 was perhaps as dramatic as parliament's decision on Wednesday to oust him.
The Zurich politician – a member of the rightwing Swiss People's Party - came into the cabinet when the centre-right Radicals in parliament backed his candidature.
Blocher's victory came at the expense of his predecessor at the justice ministry, Ruth Metzler, a member of the Christian Democrats, who had lost seats in the 2003 general election unsettling the balance of power.
A pugnacious, charismatic personality provoking admiration or dislike, the 67-year-old Blocher never hid his lack of regard for the "political class".
Those who thought he could be neutralised by giving him the post of justice minister were soon disillusioned.
The skilled speaker, who knows how to polarise, set the tone shortly after entering the cabinet by strengthening new laws on asylum and foreigners, major issues for the People's Party.
It was a process that shocked quite a few people because Blocher's decision came at a time when the House of Representatives and Senate were examining changes already worked out by Metzler.
Another project that he tackled with determination was the merger of the federal offices responsible for refugees and immigration.
Listing his infringements of the Swiss principle of collegiality became a kind of national sport for Blocher's opponents.
During his first national vote on life imprisonment for very dangerous criminals, he called for respect of the popular will and did not care if the outcome ran contrary to international law and the federal constitution.
He had little respect for the separation of powers, openly criticising Switzerland's highest instance, the Federal Court, and the asylum appeal commission.
Blocher was implicated in the highly publicised affair surrounding the resignation of the Swiss public prosecutor, Valentin Roschacher, in 2006.
Collegiality was strained on several occasions when he gave only minimum support to issues that cabinet supported but he opposed – for example the Schengen/Dublin accords on security and asylum, and the easing of naturalisation restrictions.
For his critics, there was occasionally confusion about whether he was serving the interests of the government or his party.
However, although pursuing rightwing policies, he is not considered as extreme as, for example, France's nationalist politician Jean-Marie Le Pen or Austria's Jörg Haider.
He notably earned a rebuke from the cabinet after remarks he made in Turkey on wanting to change Swiss anti-racism legislation.
Blocher - in the name of transparency – also called for cabinet votes to be made public.
A champion of "less state intervention", he styled himself as a reformer of the federal administration, which he accused of being a "protected workshop".
He had hardly stepped foot inside the justice ministry before he was changing its structure, seeking to apply methods from the business world he had used as CEO of the Ems-Chemie company.
Blocher always claimed he was making a personal sacrifice by entering government. But observers say in reality he had ambitions for a more strategic portfolio, such as minister of the interior, finance or transport.
