Duplicate Degree Certificate for ILR application

Dear board members,

I'd really appreciate your help with regard to my application for ILR in next month.

I'm on Tier 2 ICT visa for last five years, I had my visa extended during all this period.

During my last visa extension my Degree certificate (which proves my graduation was taught in English) was misplace by my company.

So I approached my university and received duplicate copy of my degree certificate. It looks exactly same as my original certificate however there is BIG stamp of 'DUPLICATE' on it.

Could you please suggest if I need to provide an explanation to UKBA giving the reason for providing Duplicate copy of my Degree certificate.

Your responce is truely appreciated.

Many Thanks
