McKell kept a dignified silence on the matter of his appointment, rather than conducting a public defence of it. Nevertheless, Chifley publicly argued that any suitable Australian should be capable of being chosen as Governor-General. Once McKell took office on 11 March, however, the continuing respect for the Crown and its representative meant that there was no further criticism. McKell carried out the usual round of his formal duties with dignity, behaved with unfailing respect towards the King himself, and succeeded in winning over all but the most inflexible. When Menzies succeeded Chifley as Prime Minister in December 1949, his relations with McKell were initially civil rather than friendly, but later on, the two men formed a cordial working relationship. Menzies even extended McKell's term by 14 months from its initial five years.
