On the economic front, Britain's monthly gross domestic product fell 0.1% in April 2026, in line with expectations, following a 0.3% rise a month ago, data from the Office for National Statistics showed. The latest figure, which marks the first economic contraction since August 2025, was driven by a fall in services, offset by growth in construction. Meanwhile, production stagnated during the month.
"While UK GDP grew by 0.7% in the three months to April, the contraction in April is more indicative of growth prospects for the economy going forward. We expect UK GDP growth to slow in the second quarter," according to Yael Selfin, vice chair and chief economist at KPMG in the UK.
The week ahead will see a barrage of economic data in the UK, including inflation, labor market figures, the Bank of England's interest rate decision, retail sales, and public sector net borrowing.
