The SNP’s Westminster spokesperson Ian Blackford has called on Boris Johnson to resign following the Downing Street party scandal.

Blackford said: “It is time for members in this House to act. If he doesn’t resign, then he must be removed.”

Johnson brushed off the remarks, saying: “I think it is very, very sad that when the public need to hear clarity from their officials and from politicians, the parties opposite are trying to muddy the waters about events or non-events of a year ago.”
