On 20 April 2021, Mercer was "sacked by text" after offering to resign at the end of Wednesday 21 April, but refusing to go earlier.^[4] In a tweet, Mercer said he was "relieved of [his] responsibilities in Government" because of his disagreements with the scope of the proposed Overseas Operations Bill.^[5][6] This new government law is designed to protect veterans from unfounded prosecutions.
