The role is a complex mix of duties and different levers of power.
The late Jeremy Heywood went over his duties in a speech to @instituteforgov in 2015. He even had a pie chart of how he spent his time...
“It doesn’t particularly change as one person succeeds another… but rather depends on the circumstances. It changes according to the tastes and preferences of the Prime Minister.”
It might seem the most routine part - helping prepare agenda and papers, writing minutes and circulating action points - But from this the role as fulcrum in Cabinet Govt flows.
This is about unlocking problems. Success in it depends on your advice being worthwhile.
“It is basically everything that is important, that is on the PM’s mind and is Number 10’s concern, where a senior civil service voice is needed.”
Supported by a team, the Cab Sec formally oversees investigations into everything from leaks to ministerial impropriety and advising depts on all manner.
It is also a lever of power
Heywood: “There is a lot of casework under this heading.”
This is where it gets complicated. There's a host of ways govt can try to tackle it.
Cab committees and central machinery are part of it, but PM will also simply want to know why things aren't working. So its also about overall gov performance
This is the job that comes with being Head of the Civil Service. It has been split from Cab Sec in the past, including for a time under Heywood:
“For many people this would be one of the biggest things they did; it is just number five on my list.”
As one put it to me, being close to the PM as Cab Sec gives you more clout to be a successful Head of the Civil Service. Being HCS gives you more levers to do what the Cab Sec does.
The Cab Sec performance manages many perm secs, but are nuances here. Perm Secs have to account to their Sec of State and to Parliament as Accounting Officer. Its a bit of a primus inter pares that reflects Cabinet Government.
They also oversee a lot of the recruitment and moves of senior civil servants, with various boards to manage it.
The civil service has a Chief Operating Officer (previously a chief executive) and their remit includes the reform agenda.
But Cab Secs also play a role. The q is whether their vision for reform is the same as others.
This was the area Heywood was initially reluctant to take on. But as he acknowledged: “This is a much bigger part of the job than I realised, but it is an important part.”
It includes select committees, supporting civil service awards and conferences. But also it is sometimes about championing and defending the role of the civil service.
The key is working out which bits of the job only they can do.
Heywood: “I simply couldn’t do everything required now in my job, John [Manzoni]’s job, and be Cabinet Office Permanent Secretary. It’s not possible in my view.”
