The Kremlin's flagship economic jamboree in St Petersburg has been upstaged by a new wave of drone attacks on the city. UK intelligence sources briefed Cabinet this morning, warning that the strikes signal a dangerous escalation in Ukraine's campaign to hit Russian soil.
The SPIEF forum, Putin's annual shop window for foreign investment, was already struggling for credibility. Western sanctions have choked off capital flows. Chinese attendance was thin. Then came the drones.
Two explosions were reported near the ExpoForum convention centre in the early hours. Air defence systems were activated. The main plenary session was delayed. Putin, due to deliver a keynote address, was kept away from the venue for security reasons. He spoke via video link instead.
Whitehall sources describe the attacks as a 'psychologically significant blow' to the regime. They come after months of relative quiet on the home front. Ukraine has been developing longer-range drones. The message is clear: nowhere is safe.
Cabinet discussed the implications in a late-night COBRA meeting. Defence sources say the strikes mirror tactics used earlier in the war against Moscow itself. They believe Ukraine is trying to undermine public confidence in the regime's ability to protect its citizens.
The economic impact is real. Several foreign investors pulled out of the forum after the attacks. The rouble weakened. Energy stocks fell. The St Petersburg bourse suspended trading for an hour.
No.10 is watching closely. The Prime Minister has ordered a review of UK air defences for major events. There is concern that similar tactics could be used against London summits or state occasions.
But the bigger picture is about Putin's domestic narrative. He has staked his legitimacy on restoring stability and greatness. Each drone that slips through his air defences chips away at that image. The opposition, though cowed, is noticing.
Labour's shadow defence secretary said the attacks show Ukraine's growing capability and Russia's vulnerability. He called for more UK support for Kyiv.
Realists in Whitehall are more cautious. They point out that the attacks, while embarrassing, are not militarily decisive. Russia has vast resources. The war is still grinding on.
But in the Westminster trenches, this is another prop knocked out from under the Russian leader. The question now is how he responds. Will he escalate domestically, or lash out externally? The next 72 hours will tell.
