Order By Descending Date

Here is my sp. I want it to order by descending date, but now it is 1st Feb it is putting this at the bottom, though January is still sorted fine. I need the dates to display in UK format dd/mm/yy

CREATE Procedure [dbo].[spRMU_CountNoDailyUsers]

AS
SELECT CONVERT(varchar, Log_DateTime, 103) AS Date_Logged_In, Log_Username as Username, COUNT(Log_Username) AS No_Logins
FROM tblUserLog
Where Log_Printed =0
GROUP BY CONVERT(varchar, Log_DateTime, 103) , Log_Username
ORDER BY CONVERT(varchar, Log_DateTime, 103) desc, No_Logins desc
GO
