This 2014 video from Britain says about itself:
British outsourcing firms G4S and Serco should be barred from bidding for government work until a fraud investigation into their failed criminal-tagging contracts is complete, a penal reform charity said on Monday. The two firms were found in July to have charged for monitoring criminals who were dead, in prison or had not been tagged at all. The Howard League for Penal Reform, a British charity, criticized that move and said on Tuesday it would hand a dossier outlining failures in recent years by both firms in delivering justice contracts to police in order to assist the SFO inquiry.

Serco, a company deeply reliant on government contracts, has hired another government insider — helping them win more lucrative public-sector gigs to mess up like the ‘track and trace’ debacle — despite being fined £23m for fraud, writes SOLOMON HUGHES
IN JULY Serco announced Dame Sue Owen, formerly a top civil servant, is becoming one of its non-executive directors. Dame Sue was permanent secretary for the Department for Culture, Media and Sport until April 2019. That made her the most senior civil servant in the department, although it isn’t a department particularly relevant to Serco’s government business.
However, Dame Sue has had a long career in government with many other Serco-relevant positions: she was a Department for Work and Pensions director-general from 2013-19 and had senior positions in the Treasury before that.
Serco itself told investors Dame Sue “has held senior positions in several government departments.”
