In the UK I am seeing searches having additional local pages injected into the listings. These additional pages are local to me.
For example google has my location as from Leeds, and the extra pages either have Leeds or West Yorkshire in the title even though I have not specified any location in my search.
It is not triggered for every search, but when it happens 3 or 4 extra pages are added which has the net result of pushing my what was the 5th result down to position 9.
I first saw this for myself on Friday 23rd, but judging from my stats it probably started happening on Tuesday 20th.
