Foreign market like that with Britain (4)
I believe the answer is:
souk
'foreign market' is the definition.
'souk' can be an answer for 'market' (souk is a kind of market). I'm not sure about the 'foreign' bit.
'like that with britain' is the wordplay.
'like that' becomes 'so' (I can't justify this - if you can you should give a lot more credence to this answer).
'with' says to put letters next to each other.
'britain' becomes 'uk' ('UK' can be a synonym of 'britain').
'so'+'uk'='SOUK'
Can you help me to learn more?
(Other definitions for souk that I've seen before include "Arab marketplace" , "Arab bazaar" , "Arab open-air market" , "Marketplace in Muslim countries" , "Eastern market" .)
