London stocks advance 0.61%, boosted by defense sector

London's stock market experienced a modest uplift on Tuesday, with the benchmark FTSE 100 index climbing 0.61%. The gains were largely propelled by a surge in the defense sector, as investors anticipate increased military spending commitments from G7 nations gathering at a summit in France.

The FTSE 100 added 63.59 points to close at 10,494.21. In contrast, the secondary FTSE 250 index saw a slight dip, retreating 0.15% to 23,326.58 points.

Aerospace and defense specialists Rolls-Royce Holdings and BAE Systems were notable gainers, rising 2.55% and 2.20% respectively. Their performance reflects market optimism surrounding potential boosts in defense investment, with attention also focused on whether the United Kingdom will increase its own military expenditure.

Other companies showing positive movement included mining firm Endeavour Mining, which advanced 2.85%, and property developer Persimmon, closing 2.47% higher. However, the session was not uniformly positive. Telecommunications group BT fell 2.69%, food producer Associated British Foods dropped 1.69%, and data analytics firm Relx saw its shares decline by 1.31%.
