Theresa may heads to south africa to eye up post brexit trade deal
That's not accurate. Theresa May, the former Prime Minister of the United Kingdom, did not head to South Africa to eye up a post-Brexit trade deal.
Theresa May was the Prime Minister of the UK from 2016 to 2019, and during her tenure, she was focused on negotiating the UK's withdrawal from the European Union (Brexit). She resigned as Prime Minister in July 2019, and was succeeded by Boris Johnson.
It's possible that you may be thinking of Boris Johnson, who has been the Prime Minister of the UK since July 2019, and has been actively engaged in negotiating trade deals with various countries, including South Africa, as part of the UK's post-Brexit trade strategy.
In fact, in September 2020, Boris Johnson visited South Africa as part of a tour of African countries, where he discussed trade and investment opportunities with South African President Cyril Ramaphosa. The two leaders agreed to strengthen trade ties and cooperate on issues such as climate change and security.
It's worth noting that the UK and South Africa have a long history of trade and economic cooperation, and there are ongoing efforts to strengthen and expand their trade relationship in the post-Brexit era.
