ELECTION FOR BORIS JOHNSON'S SUCCEEDER WILL BE A ‘TIGHT CONTEST’: NILE GARDINER

NILE GARDINER: Undoubtedly Liz Truss is heading for Downing Street. She has a huge lead in the Conservative Party leadership contest. She currently has a lead, I think of around 30 percentage points over Rishi Sunak, who is her chief rival to become the next prime minister. Liz Truss I think will be the prime minister to be announced tomorrow. She'll take office on Tuesday and I think she'll be a very strong and robust leader for Great Britain. She is a Thatcherite, a politician with strong conservative principles. She's a tax cutter, she believes in limited government, and reining in government spending as well. I think she'll be exactly what Great Britain needs at this time, a very strong leader on the world stage at home and abroad, and a staunch Thatcherite as well.
