Soviet-born British businessman Alexander Temerko, who has given more than £1.2 million to the Tories over seven years, told The Mail on Sunday that protecting the economy should be the priority.

‘Without a strong economy, the NHS will be in grave danger. We must get people back to work immediately. The Civil Service must do the same,’ he said.

‘The Civil Service must be the example of the Government’s policy of a full return to work. This is vital for our economy. Workers in offices increase productivity in jobs and boost local economies that rely on them. Safeguarding the health of our economy is the key to saving our public health and society, too. We need mass testing, robust track-and-trace, and safe offices to get our economy working again.’
