panicing as about to submit AN form via post

Hi,

i received ILR card last year.

Is that the same as "BRP" card. I don not have BRP card anymore as i submitted it with my application last year (for Indefinite leave to remain application) and never received it back . not sure if i was even supposed to receive it back and now panicing about it.

can someone calm my nerves?

Is ILR card all i needto submit with my application?

ILR card = BRP card stating 'Indefinite Leave to Remain'.

This will be sufficient to submit as proof of ILR.

thanks.
