Anxious to avoid excessive concentration of power similarly to Somerset, following his fall
Lord President of the Council
Initially unclear what type of regime he was going to preside over
Many of his key supporters in the coup had been conservatives who hoped for a regency led by Princess Mary
His second coup, directed at the conservatives, made the nature of the regime clearer
Likely that he acted because he feared that he himself might be ejected by the conservatives
The purging of the conservatives Southampton and Arundel, Cranmer's support, and the King's own increasingly assertive Protestantism determined the religious character of the regime
Warwick promoted to Duke of Northumberland
Already Lord Chamberlain
Appointed his own hardman, Sir John Gates as Vice-Chamberlain of the household to ensure his control over the court
Operated an effective government via Privy Council, undoubtedly made easier by the expulsion of the Earl of Southampton
Paget drew up guidelines for this, some of which Northumberland instituted, although Paget was increasingly excluded from the decision-making process
William Cecil, initially one of Somerset's men, transformed into Northumberland's key administrator
Broadly collective government didn't survive Somerset's attempt at a counter coup
Somerset readmitted to the council
Plotted to recover his old position but was outwitted by Northumberland
Somerset was executed which according to Dale Hoak saved England from a revival of the chaos that had characterised the protectorate
Northumberland became less conciliar in his approach to government in reaction
Presumed enemies e.g. Paget (sent to the Tower) were removed from the Council
Power strong with Northumberland and his henchman Gates who had possession of the dry stamp with which he could affix the king's signature to documents
