BT Group (LSE:BT.A) ranked among the stronger large-cap performers in London on Thursday, standing apart from a benchmark that drifted lower overall.
Banking shares came under particular pressure after fresh inflation figures trimmed Bank of England rate expectations, making the telecoms advance more notable by contrast.
