IFR Separation from unknown VFR traffic

[ATCO2]

Hi,

I have a simmilar question. What to do in TMA class E airspace, where VFR is not supposed to have even radio. They fly with no squawk on or if they have it on Mode C is not verifyed. I know that they have a radio but they operate in TMA class E with no obligation to call anyone. In that TMA, what I have seen, many IFR traffic is vectored to the ILS approach. ATCOs there pass traffic info as unknowen traffic and do a lateral separation with unknowen one. I think they are correct.

I would like to hear your opinion about this.

Regards,
