How many British citizens have applied for passports of other EU countries because of the Brexit vote and how many have moved to other EU countries?

I asked “What monitoring is the UK Government doing to find out how many UK citizens have applied for passports of other EU countries since the referendum .. how many UK citizens have .. moved to other EU member states”
“The Department for Exiting the European Union (DExEU) does not hold information in the scope of your request” Our Govt really is clueless about the effect on British people. This from a Government that bangs on about immigration but UK Government has no records of UK migrants.
National Statistics, the official UK Government statistics body, do not keep any record of British citizens leaving the UK. I travel abroad between one and six times a year and never once, ONCE, have I ever been asked whether I am leaving and coming back.

Policies for dealing with buddleia.

For some time I’ve been very concerned about the damage caused by the pretty, bee friendly but highly invasive plant, buddleia. I was going to ask my City Council if they had policies on this topic but decided to start with the national authorities I thought might be responsible.
Here are links to my questions and answers. The Environment Agency does not deal with these plants unless they are causing a blockage within a watercourse.
“Invasive and injurious plants are not reportable to the Environment
Agency.
Only if weeds are causing a blockage within a watercourse and flooding is
imminent would be reportable to our incident communication service on 0800 807060.”
They then posted useful information on harmful weeds and invasive non-native plants.

The Department for Environment, Food and Rural Affairs (DEFRA) does not have the information at present because “Defra is currently developing a rapid risk assessment for Buddleia which will assess the associated risks and impacts of the species to GB.” So it looks like they are taking this problem seriously, which is good.
