In the UK the answer is: not always.

Article 8(1) of the European Convention on Human Rights (ECHR) states "everyone has a right of respect for his private and family life, his home and his correspondence". However, this is not an absolute right: it is a qualified right and interference with such privacy may be justified. Article 8(2) provides that a public authority shall not interfere with the exercise of the right to privacy "except such as is in accordance with the law and is necessary in a democratic society:

• in the interests of national security, public safety or the economic well-being of the country;

• for the prevention of disorder or crime;

• for the protection of health or morals;

• for the protection of the rights and freedoms of others."

The Human Rights Act 1998 (HRA 1988) incorporates Article 8 of the ECHR into UK law and all “public authorities” are expressly subject to the HRA 1998.

The definition of "public authorities" is very broad, going well beyond the narrow categories of central and local government and encompassing any person who carries out functions of a "public nature".

Therefore, if the scenario applicable to Mrs Clinton in the US were to be transferred to the UK, the argument adopted by Mrs Clinton may have little chances of success in the light of the said provisions.
