Government's July surplus at 18-year high per BBC News

The BBC report https://www.bbc.co.uk/news/business-45256075 through gritted teeth that:

'The government's finances were in surplus by £2bn last month, the biggest surplus for July in 18 years, official figures show.

The figure was up from a surplus of £1bn a year ago.

At the same time, borrowing in the April-to-July period fell to its lowest level since 2002.

Analysts said the reduction in borrowing should give Chancellor Philip Hammond extra money to play with in the Budget this autumn.

Borrowing for the financial year so far has reached £12.8bn, £8.5bn less than in the same period in 2017, the Office for National Statistics said.'

Weren't we told that a win for Brexit would bring destruction to the UK economy, I note that the BBC don't recall those warnings in this piece.
