Edward called for a fresh military campaign for Scotland, but this idea was quietly abandoned, and instead the king and the barons met in August 1308 to discuss reform. Behind the scenes, Edward started negotiations to convince both Pope Clement V and Philip IV to allow Gaveston to return to England, offering in exchange to suppress the Knights Templar in England, and to release Bishop Langton from prison. Edward called a new meeting of members of the Church and key barons in January 1309, and the leading earls then gathered in March and April, possibly under the leadership of Thomas, 2nd Earl of Lancaster. Another parliament followed, which refused to allow Gaveston to return to England, but offered to grant Edward additional taxes if he agreed to a programme of reform.
