(Bloomberg) — U.K. jobless claims increased last month as coronavirus pandemic began to have an impact on the labor market.

Claims rose 12,200 compared with a 5,900 gain in February, the Office for National Statistics said Tuesday. The claimant count rate was 3.5% compared with 3.4%.

Unemployment is sure to keep rising after the government extended the lockdown for at least three more weeks, ensuring that much economic activity will remain on hold. Output could shrink 35% this quarter, according to the Office for Budget Responsibility.

The International Labor Organization jobless rate was 4% in the three months through February. That may rise to 10% after the pandemic, the fiscal watchdog said.

Wage growth slipped to 2.8% in the December-February period from 3.1%, the ONS reported.
