Activists in the UK have expressed concern that the British government might cancel one of the biggest Palestinian events in the country.

This is while the Palestinian cultural event is expected to draw 10,000 people in London in July.

British officials have warned event organizers Friends of Al Aqsa (FOA) that the two-day Palestine Expo 2017 event at the Queen Elizabeth II Conference centre (QE2) in London could be cancelled by the Department for Communities and Local Government.

“We look forward to welcoming over 10,000 people to the biggest Palestine event in Europe to celebrate Palestine culture and heritage,” said FOA spokesperson Shamiul Joarder.

“The government's move appears to be a clear attempt to censor all things Palestinian, be it culture, heritage or politics.”

Joarder went on to say that any threat to shut down the event is inexplicable and that there is no justification for such action.

Al Jazeera said it had obtained a letter written by the lawyers of an Israeli lobby group, known as Jewish Human Rights Watch, addressed to QE2, which accuses FOA and a co-organizer, the Palestinian Solidarity Campaign, of supporting “Jew hate”.

"Our client is certain that this event is a front for Jew hate and that the main groups (Friends of Al Aqsa and the Palestine Solidarity Campaign) are organisations promoting Boycott, Divestment and Sanctions (BDS) in relation to Israel, a known anti-Semitic movement," stated a letter by the lobby group's solicitors.

FOA and PSC groups have rejected all the accusations. FOA said it would take legal action over the “defamation”.
