SIR - In June 2016 the Leave campaign promised us that departing for the EU would free up £350m per week that might be spent on the NHS.

New research by the Centre of European Reform has discovered that already the Brexit threat has cost significant loss of growth to the UK economy. This amounts to £26 billion per year – or a cost of £500,000 per week. And this is all before we have actually left.

The false promises of the Leave campaign are thus further exposed.

To the above we can add the fall in the exchange rate of the pound that means that the rising cost of imports has reduced the value of household real income as prices in the shops go up. Brexit-induced inflation has made UK families worse off by about 5per cent.

Sadly, as I go about my business of trying to persuade folk to demand a “People's Vote” I come across some who are determined to stick by their “Leave” vote of over two years ago. More encouragingly, there is a growing number of Leavers who are willing to re-asses and base their judgement on the facts that have emerged since June 2016.
