June figure of £20.7bn comes as chancellor prepares for autumn budget where she may have to make tax rises
The UK government borrowed more than expected in June amid pressure on the chancellor, Rachel Reeves, to repair the public finances.
Figures from the Office for National Statistics (ONS) show public sector net borrowing rose to £20.7bn. This was £6.6bn higher than the same month a year earlier and the second-highest June borrowing figure since monthly records began in 1993. City economists had forecast borrowing to increase to £16.5bn.
