A Downing Street spokesperson said:
In separate calls, the Prime Minister this afternoon spoke with President Macron and President Trump.
The three leaders agreed that the military strikes taken against the Syrian Regime’s chemical weapons sites had been a success.
The Prime Minister welcomed the public support which had been given by fellow world leaders for the strong stand the UK, France and the United States had taken in degrading Syria’s chemical weapons capability and deterring their use; defending global rules; and sending a clear message that the use of chemical weapons can never become normalised.
