Ruby McGregor-Smith and Ajay Chowdhury have been appointed as non-executive directors to the Department for Culture, Media and Sport (DCMS) board by culture secretary Maria Miller.
They replace Peter Bazalgette, now chair of Arts Council England and Lord Coe, who was invited to attend DCMS Board meetings by virtue of his position as chair of LOCOG.
McGregor-Smith became the first Asian female chief executive in the FTSE 250 when she reached that position at MITIE - a strategic outsourcing company.
Chowdhury, currently the chair of global digital media company ComQi, brings decades of experience in the digital and technology industry and will help the department roll out the UK's broadband programme.
