Check - most big EU airports don't generally mix visuals with instrument apps, partly as it introduces too many variables and would reduce flow rate if a pilot creates different spacing on a visual than ATC anticipated, but mostly because the EU doesn't enjoy the positive attitude towards aviation that the US does, and residents and authorities are itching to punish crews and airlines for noise violations. ATC are very restricted as a resulting in the routings they can offer in many airports. Besides, EU airlines tend to be highly procedural, at least with heavies (a whole other cultural discussion that has been had many times!). The smaller airports with medium jets and regionals are a bit more flexible as their arrival rates are low enough that ATC can correct for such cases. However, given the inaccuracies already pointed out in his post, I wouldn't credit his claim of the delays being due to the ILS with much reliability.
