Edward sent assurances to the Pope that the conflict surrounding Gaveston's role was at an end. On the basis of these promises, and procedural concerns about how the original decision had been taken, the Pope agreed to annul the Archbishop's threat to excommunicate Gaveston, thus opening the possibility of Gaveston's return. Gaveston arrived back in England in June, where he was met by Edward. At the parliament the next month, Edward made a range of concessions to placate those opposed to Gaveston, including agreeing to limit the powers of the royal steward and the marshal of the royal household, to regulate the Crown's unpopular powers of purveyance, and to abandon recently enacted customs legislation; in return, parliament agreed to fresh taxes for the war in Scotland. Temporarily, at least, Edward and the barons appeared to have come to a successful compromise.
