Not proud to be British today.
As the referendum is not legally binding, so I would think UK actually leaving EU would require parliament to approve new legislation, which parliament and/or House of Lords may not pass, and would presumably first/alongside need Scotland and NI to have referendums on their (partial/further/full) independence, I don't actually know where all this is going to lead to. At a minimum it will be a huge waste of time, money and effort when there are real problems to deal with (take your pick from obesity, migrant crisis, air pollution, climate change, public debt, NHS reform etc. etc.) that will therefore get less focus.
