He appeared on Thursday at Westminster magistrates court to face two allegations of encouraging the commission of an offence between August 31 last year and March 31 this year.
Prosecutor Tom Broomfield said the charges relate to Hendron “encouraging the supply of Class A – crystal methamphetamine – and Class C – GBL – drugs from a former client of Mr Hendron, who was a practising barrister at the time.”
Hendron also faces an allegation he offered to supply crystal meth between January 26 and February 2, 2018, and possession of the same drug at an address in Dagenham, east London, on May 5 this year.
The barrister, who was called to the Bar in 2006, represented himself at the magistrates court hearing, speaking to confirm his name, date of birth, and address in Covent Garden, central London.
He did not enter pleas to the charges but said: “It all seems frightfully serious.”
Hendron represented Ms Dorries in a 2009 civil lawsuit, and he was part of Ms English’s unsuccessful employment tribunal claim against Lord Alan Sugar.
His criminal case was sent to Woolwich crown court for a preliminary hearing on September 22.
