Chuka Umunna has launched a new watchdog aimed at ensuring Leave campaigners stick to the promises they made during the Brexit campaign.
The prominent Remain campaigner and Labour MP has joined forces with a cross-party group of like-minded MPs and others to try to put pressure on the withdrawal side to come good on their referendum pledges.
"Now that we have voted to leave the European Union, they think you are going to forget those promises and those pledges that were made. We are determined to ensure their promises are scrutinised and they are held to account for all the pledges that were made," Umunna said.
He said Vote Leave Watch would be of equal value "whether you are the 48%, bitterly disappointed at the result, which, of course, we have to accept, or you're the 52% who voted for us to leave, who want to know that the promises made to you are delivered on. For example the promise that there would be £350 million extra every week going to our NHS."
But what exactly are the pledges that are under threat?
1. Promising £350 million a week to the NHS.
The Vote Leave campaign said they would send the £350 million they claimed was given to the EU each week to the NHS. They had a campaign bus with the slogan "We send the NHS £350 million a week, let's fund our NHS instead".
After the vote MEP Daniel Hannan of Vote Leave said Britain should be part of the single market and keep free movement of labour.
3. Saying the economy would be stable.
Vote Leave repeatedly reassured voters that leaving the EU would strengthen the economy.
Michael Gove said: "With growth rates so low in Europe, with so many unemployed and with the nature of the single currency so damaging, freeing ourselves from that project can only strengthen our economy."
When economic experts pointed out that the evidence showed Brexit would lead to economic harm and instability, Gove said "100 German scientists in the pay of the government" said Einstein was wrong, effectively comparing the British government to the Nazis.
However, when the results were announced the pound hit a 31-year low against the US dollar, £124 billion was almost immediately wiped off the stock market, there were reports of banks moving staff out of London, companies reported cancelling contracts, the UK's credit rating was downgraded from its triple A status and the share prices of banks and companies like RBS, Virgin and Barclays dropped by around 30%.
However, Boris Johnson confusingly said the economy was fine.
We think that's quite a lot for Vote Leave Watch to be getting on with for now.
