UK Covid Inquiry: Humza Yousaf admits to 'winging it' as health secretary during pandemic as Scottish Government leaders accused of 'pettiness'

The Scottish Government’s leadership was accused of “pettiness” as fresh messages emerged of Humza Yousaf admitting to “winging it” in his early days as health secretary at the height of the Covid pandemic.

Calls for national clinical director Professor Jason Leitch to be sacked have also grown after private WhatsApp messages with Mr Yousaf were also published in which he accused one Tory MSP of "harrumphing like a child" and called a Labour MSP a "smarta*se".
