what duties does the home secretary have to parliament
Home Secretary The Home Secretary is responsible for the internal affairs of England and Wales, and for immigration and citizenship for the United Kingdom. The remit of the Home Office also includes policing in England and Wales and matters of national security, as the Security Service (MI5) is directly accountable to the Home Secretary.[1] Formerly, the Home Secretary was the minister responsible for prisons and probation in England and Wales; however in 2005 those responsibilities were transferred to the newly created Ministry of Justice under the Lord Chancellor.
Cabinet (government) In parliamentary democracies, several policies exist: cabinet members must, must not, or may be members of parliament, depending on the country. In the United Kingdom, cabinet ministers are mandatorily appointed from among sitting members of the parliament. In countries with a strict separation between the executive and legislative branches of government, e.g. Luxembourg, Switzerland and Belgium, cabinet members have to give up their seat in parliament. The intermediate case is when ministers typically are members of parliament, but are not required to be, as in e.g. Finland. The candidate prime minister and/or the president selects the individual ministers to be proposed to the parliament, which may accept or reject the proposed cabinet composition. Unlike in a presidential system, the cabinet in a parliamentary system must not only be confirmed, but enjoy the continuing confidence of the parliament: a parliament can pass a motion of no confidence to remove a government or individual ministers. Often, but not necessarily, these votes are taken across party lines.
