(2)After the record of the plea of "Guilty" on a charge (if the trial does not proceed on any other charges), the Court shall read the summary of evidence, and annex it to the proceedings or if there is no such summary, shall take and record sufficient evidence to enable it to determine the sentence, and the reviewing officer to know all the circumstances connected with the offence. The evidence shall be taken in like manner as is directed by these rules in case of a plea of "Not Guilty".
