Although primarily famous for being British Prime Minister Tony Blair’s wife, Cherie Booth QC — who practises under her maiden name — is also one of the UK’s top lawyers.

Specialising in areas including human rights, public law and employment law, the 52-year-old is recommended by UK law directories as having “great presence in court” being “incredibly sharp” and “widely acclaimed for her superb grasp of judicial review and other public law remedies.”

According to Becky’s father Dave Middleton: “Having her certainly does boost the confidence, there’s no doubt about that. The fact of the matter is you get the best person you can to do the job.”

Ms Booth has been involved in a number of high profile cases.

Last year, she successfully represented a teenager who claimed her school in England acted illegally in barring her from lessons for wearing traditional Muslim head-to-toe dress.

The Court of Appeal agreed Shabina Begum’s rights had been violated - although the House of Lords later overturned this decision.

In the 90s, Ms Booth represented a gay woman at the European Court of Justice, arguing that a train company discriminated against her on grounds of sexual orientation.

Ms Booth argued that Lisa Grant was refused a rail pass for her partner Jill Percey because they were both women, but would have been given a pass if one was a man. The judges ruled against her.

She met Tony Blair, leader of the ruling Labour Party, when they were studying law, and they have been married for 27 years. They have four children with the youngest.

She has proved a favourite target for the British tabloid press, which has criticised her on topics ranging from her dress sense to a propensity for being caught in unflattering photographs. She was mocked when she was fined for fare dodging on a train in 2000, and lambasted in 2002 over a controversial property deal with a convicted fraudster.

Another British QC, James Guthrie, will put the case for the Director of Public Prosecutions. Mr. Guthrie, 57, is listed in legal directories as a leader in the fields of civil liberties and human rights and has acted in many cases throughout the Caribbean.
