Who? Tessa Gregory, 33, public law and human rights solicitor at Birmingham firm Public Interest Lawyers.

Why is she in the news? Acted for Ekaterina Zatuliveter, 26, who was arrested and served with a deportation order in December 2010 because, MI5 believed, she was a Russian spy. The case against her was given weight by her relationships with older men, including Mike Hancock MP, who has sat on the parliamentary defence select committee and the All-Party Parliamentary Group on Russia.
