Wentworth was recalled to England in September 1639. He was expected to help sort out the problems that were growing at home: namely, bankruptcy and war with the Scottish Covenanters, and became the King's principal adviser. Unaware how much opposition had developed in England during his absence, he recommended the calling of a parliament to support a renewal of the war, hoping that by the offer of a loan from the Privy Councillors, to which he contributed £20,000, he would save Charles from having to submit to the new parliament if it proved truculent.
