On August 11, 197S, wе granted leave to Stoller Fisheries, defendant below, to pursue this interlocutory appeal from the order of the District Court 1 denying Stoller’s motion to amend its answer to raise two further affirmative defenses and to assert a counterclaim. 2 28 U.S.C. § 1292(b). At the same time, we expedited the aрpeal, which was argued and submitted September 16, 1976. We now affirm the District Court.
On July 31,1975, a complaint was filed by Mercantile Trust Company National Association (“Mercantile”) seeking to recover sums alleged to be due from Inland Marine Products Corporation, alleging a right of recovery for suсh debt from Stoller under a guarantee agreement, and claiming a further sum from Stoller arising out of payments made by Mercantile under letters of credit on behalf of Stoller. Between the filing of the complaint and January 30, 1976, Stoller filed two amended answers asserting fourteen affirmative defеnses.
Discovery activity by Stoller, as disclosed by the record, was slow in coming, even though on November 13, 1975, the case was set for jury trial on March 1, 1976. Stоller’s first interrogatories to plaintiff were filed December 24, 1975. Not until February 17,1976, did Stoller file notice of taking its first deposition. On February 18, 1976, *1012 the March 1 setting was vacated and the cause reset for trial on May 10, 1976. In the interim, between February 18 and April 23, only one deposition was taken by Stoller. On April 23, the District Court vacated the trial setting a second time and reset the case for July 12, 1976. Stoller took two depositions on April 27 and April 29. No further formal discоvery by Stoller is disclosed in the record until July 28,1976. On May 21, 1976, Mercantile filed a motion to compel discovery, which was granted on June 2, after the District Court had again reset the case for August 16,1976. On July 12, 1976, almost one year after the filing of the complaint, Stoller moved to file an amended answer to assеrt a counterclaim and additional affirmative defenses. 3 The District Court denied the motion, citing “undue delay by [appellant] in seeking to file this amendment,” and concluding that to allow the amendment would not be in keeping with the rule of justice stated in Fed.R.Civ.P. 15(a). 4
The proper test in reviewing an ordеr denying leave to amend under Fed.R. Civ.P. 15(a) is whether the District Court has abused its discretion.

v.
Hazeltine Research, Inc.,
Mere delay is not a reason in and of itself to deny leave to amend. There must be found some prejudice which would result to others if leave wеre to be granted.
Zenith Radio Corp. v. Hazeltine Research, Inc., supra,
We cannot say that the District Court abused its discretion in this case. What amounts to “undue delay” will, of course, vary with the facts. Stoller had ample time in which to develop its defenses and to assert its counterclaim. That it failed “to cure deficiencies by amendments previously allowed” as a result of its leisurely approach to discovery only reinforces the conclusion that the District Court exercised its discretion in a reasonable manner under these facts.
See Standard Title Ins. Co. v. Roberts,
The order ruled upon is, of course, an interlocutory one. If the District Court cannot reschedule a trial sеtting at an early date, it may wish to reconsider its order, as undue delay may no longer be a factor. We simply say at this time that Stoller, armed with its fourtеen affirmative defenses, has not been unfairly prejudiced and the District Court did not abuse its discretion.
Notes
. The Honorable H. Kenneth Wangelin, United States Distriсt Court for the Eastern District of Missouri.
. The District Court also denied Stoller’s motion to extend discovery time previously fixed at July 28, 1976, so as to permit depоsitions commenced on July 28, 1976, to be completed. The District Court properly refused to include this issue in its interlocutory certification and we decline to consider it here.
. Briefly stated, the proposed counterclaim alleged that Mercantile had honored letters of credit issued by Stoller to pay invoices presented by the beneficiary which Mercantile knew to be fictitious, with resulting damage to Stoller’s business. The counterclaim is in five separate counts, all of which are variants of the original contention. The additional affirmative defenses are (1) thаt the guarantee agreement was without consideration and unauthorized and (2) that the guarantee agreement was limited as to time and amount, both of which limitations were breached by Mercantile.
. Fed.R.Civ.P. 15(a) provides:
(a) Amendments. A party may amend his pleading once as a matter of course at any time before a responsive pleading is served or, if the pleading is one to which no responsive pleading is permitted and the action has not bеen placed upon the trial calendar, he may so amend it at any time within 20 days after it is served. Otherwise a party may amend his pleading only by lеave of court or by written consent of the adverse party; and leave shall be freely given when justice so requires. A party shall plead in rеsponse to an amended pleading within the time remaining for response to the original pleading or within 10 days after service of the amended pleading, which ever period may be the longer, unless the court otherwise orders.
. While it has been held that leave to file an omitted cоunterclaim must be obtained in conformity with Fed.R.Civ.P. 13(f), the same liberal standards for consideration would seem to apply under Rule 13 or under Rule 15.
