New No 10 policy chief says tax cuts are a priority Boris Johnson’s new Policy Chief Andrew Griffith has declared that delivering tax cuts is now among the top priorities for the PM’s administration. He wrote on the Conservative Home website: "Families want to hear about our plans to grow employment, tackle the NHS backlog, control our borders, make their streets safer, bring down the cost of living and return rapidly to the point when we can cut taxes to let everyone keep more of their own money - all policies rooted in strong Conservative values.”
