Quote:Downing Street has rejected calls to cancel President Donald Trump's proposed state visit to the UK after a US clampdown on immigration.
A source said a rejection would be a "populist gesture", adding that the invitation had been accepted and scrapping it would "undo everything".
Labour leader Jeremy Corbyn said PM Theresa May would be failing the people if she failed to postpone the visit.
A petition to stop it has gathered more than 900,000 signatures since Saturday.
Only 100,000 signatures are needed for Parliament to consider debating a petition.
