The Health Secretary insisted that Brooks Newmark received no special treatment as he brokered a deal for international firms to supply millions of pairs of goggles to the NHS last year.
Mr Newmark, 63, a father of five, quit just months after being made minister for civil society in 2014 after he was exposed as having exchanged lewd photographs with a male journalist posing as a glamorous 20-year-old Tory PR woman.
A Freedom of Information probe by the Sunday Times today discovered National Audit Office emails showing that last May, at the height of the first Covid lockdown, he lobbied the Government on behalf of a Hong Kong firm.
