All senior civil service roles will now be advertised externally to attract more talent from the private sector, as Michael Gove launches a new Government declaration on Whitehall reform on Tuesday.

The plans are among a series of changes that will be signed off at the first ever joint meeting of the Cabinet and civil service leaders from Government departments.

The "Declaration of Government Reform", which was set in motion by Mr Gove and Dominic Cummings, Boris Johnson’s former top aide, will also include the relocation of 22,000 civil service roles out of London by 2030. 

New training will be provided to civil servants and ministers to bolster their expertise in digital, data, science and project delivery, with a new training campus due to be established. 

To further improve the delivery of Government projects and programmes, an evaluation task force will be set up in the Cabinet Office to ensure "proper scrutiny of real world results".

The civil service fast-track graduate scheme will be updated, with apprenticeships introduced, while pay, reward and performance management for civil servants will also be overhauled. 

Permanent secretaries of departments will have their performance overseen by the Prime Minister and the Cabinet Secretary, Simon Case. 

In a speech on Tuesday, Mr Gove, the Chancellor of the Duchy of Lancaster, will point to the Covid-19 crisis and the weaknesses it exposed in Government as evidence of the need to "deepen and accelerate our programme of reform".

He will go on to say: "On some past occasions, it has been regrettable that reform overall was seen as something driven by politicians, against the mulish opposition of bureaucrats. It is a missed opportunity when reform is felt as something done by ministers to civil servants, rather than with them. 

"And greater openness in the deployment of outside talent to drive progress should never be understood as somehow a replacement for or usurpation of the vital role civil servants play."

Mr Johnson said on Monday: "As we look ahead to the opportunities ahead of us to build back a better and fairer Britain, we owe it to the people of this country to make sure their government is best equipped to deliver on their priorities.

"That’s why we are launching our blueprint for reform – to keep building on our expertise, modernise how government is run and transform this country for the better."
