George the IV makes Peace with France

In 1811, so I am reading, George IV became Prince Regent of the UK. He dashed the hopes of his Whig admirers by retaining the existing Parliament rather than replacing it with handpicked Whig members. I am further given to understand the Whigs were in favor of negotiating a peace with France at this time. So my question is why did George retain the old government and what (if anything) could be changed to create a peace between France and England around this time?
