Imran Khan has told Britain he will retrieve wealth looted from his country and stashed in the UK by corrupt Pakistani politicians.

The former cricketer used his first meeting with British officials since his general election win to say he would pursue laundered money.

New anti-corruption UK legislation designed to target oligarchs and international crime could be used to freeze or seize property and assets if there is evidence it was bought with illegal or unexplained wealth.

Attacks on the greed of Pakistan's dynastic ruling elite have been the cornerstone of the populist anti-corruption drive which has swept Mr Khan to power.

He has denounced the political class for siphoning off money from public sector institutions and contracts and then salting it away overseas.

The issue has dominated Pakistan's politics since the Panama Papers leak linked former prime minister Nawaz Sharif's family to offshore companies and four Park Lane flats.
