British citizens living in Thailand may well wish to register as overseas voters. Information is available at https://www.gov.uk/voting-when-abroad.
All British citizens overseas should have the vote without the restriction against those who have been living abroad for more than 15 years. British government policies on pensions, higher education, access to the NHS, etc, all affect those living abroad.
Everyone is welcome to submit their views on this policy at https://form.jotform.com/82578072072156.
There is the need to set up an overseas constituency so that the many Britons abroad can elect their own MP and have their interests properly represented.
