would have hindered Henry if he didn't use it in the way that he did - shown in the fact he only called 7 times, suggests this democratic way of ruling and delegation of power could have threatened his personal authority
meant he could get support from nobles, they could not turn their back on his policies (because they agreed to them), acted as an inducement for good behaviour from nobles
sir william stanley (lord chamberlain) was involved in PW threat - privy chamber limited number of nobles with political influence - reduced chance of spying since he knew them all more intimately
Henry Percy was killed in the Northern Rebellion - it would neutralise the area, (Thomas Howard) Surrey didn't have land nor strong support so chance of another rebellion was low [Surrey was imprisoned after BoB then given chance to escape but didn't proving his loyalty]
