GBPUSD - Reaction to 1.2750 post-CPI

Watching $GBPUSD closely after the CPI numbers this morning. The initial pop above 1.2750 was short-lived, with price quickly retracing. It now appears to be forming some support around the 1.2720 level. The question is whether this is merely a retest of a broken resistance, or if sellers are ready to push it back towards 1.2680. Volume on the rejection was notable. Any thoughts on the likelihood of a sustained move lower from here given the mixed data?
