The £350m-a-week figure comes from the Office for National Statistics, which said the UK contributed £365m a week to the EU in 2014 (or £335m on average in 2010-14).
So what's the real figure?
The UK Statistics Authority dealt with this in the letter they sent last month.
They started with the £19.1bn total figure handed over from the British government to the EU in 2014 (£365m a week).
Then they took away certain benefits to the UK in three steps:
1. Add the government's rebate
This was worth £4.4bn in 2014.
Factor it in and you get Britain paying £14.7bn to the EU (£285m a week).
If you take an average for 2010-2014 you get Britain paying £13.9bn (£270m a week).
2. Add direct EU payments to the public sector
These were worth £4.8bn in 2014.
Factor them in too and you get Britain paying £9.8bn to the EU (£190m a week).
If you take an average for 2010-2014 you get Britain paying £8.9bn (£170m a week).

increases the £170 million a week figure to that already stated.
