Mr Clement was leader of Bexley Council from May 2006 to May 2008
A former mayoral aide forced to resign in a row over expenses has been charged with five offences relating to the use of a credit card.
In June, Ian Clement, 44, stepped down as London's deputy mayor for external relations following allegations about his use of a corporate credit card.
Mr Clement, from Crayford, is alleged to have paid for groceries and meals out on his corporate credit card.
He will appear at City of Westminster Magistrates' Court on Tuesday.
He served as leader of Bexley Council from May 2006 until May 2008, when he took up his post at City Hall.
Personal use of a corporate credit card is a breach of City Hall regulations.
