I don't know about the rest of them but Elton John and the Blairs both have more than one house in the UK, Elton also has houses in France and the USA, and Tony is forever holidaying at grace and favour homes of 'friends' in Tuscany and the Carribbean. These people can (and do) get out of Britain for a good part of the year, but the people who Brexit will affect most are the British public, the majority of whom voted to leave the European Union and are quite happy to live with the consequences of leaving the EU.
I voted to remain, but I am not a Remoaner. I accept the vote, and now want Brexit to be a success for our country. Project Fear rolls on, and those chewing the sour grapes continue bitterly talk down the economy, refuse to project a positive vision of Brexit and criticise and begrudge the voting public. The bitter ones should, I believe, accept the result of the Referendum and get put their efforts and mouths into making Brexit a success. Britain always bounces back, whatever difficulty or crisis it has thrown at it- we will get through Brexit and come out stronger for it, despite the naysayers and the "Yesterdays men" listed above.
