Britain's foreign minister David Lammy said he was seeking answers from Hong Kong and Chinese authorities on Sunday after an opposition member of parliament, Wera Hobhouse, was denied entry to the Chinese territory and former British colony.

It comes after after two Labour MPs, Abtisam Mohamed and Yuan Yang, were refused entry to Israel while on a trip to the occupied West Bank this month. Ms Hobhouse's treatment is likely to raise further questions about the government's engagement with China.
