Prime Minister David Cameron avoided any direct response to questions of his tenure amid further resignations over the hacking scandal.

When asked by The Daily Mail if he was considering his position as Prime Minister Mr Cameron said: "The British government, in terms of the phone hacking scandal, has taken all of the appropriate actions. We have set up a judicial inquiry, we have made sure there is a properly funded police investigation. We have published huge amounts of information about any meetings between politicians and senior media executives. So i think we have given a very clear answer."

Mr Cameron fielded questions at a business Q&A session at the Johannesburg Stock Exchange as part of his South Africa trade tour.

Mr Cameron added: "Parliament is going to come back on Wednesday, I'm going to make a big statement updating what we are doing with the judicial inquiry. I will be able to answer any of the questions that have come up in the last couple of days. I feel I have been out there in Parliament, in press conferences fully answering the questions, fully transparent, very clear about what needs to be done - making sure that Britain gets to the bottom of what has been a terrible episode in terms of what newspapers have done, hacking into private data. And also some very big questions about potential police corruption. We need to get to the bottom of those."

Speaking earlier today, Labour Leader Ed Miliband said: ""Sir Paul Stephenson has taken responsibility and resigned over the employment of Mr Coulson's deputy, while the prime minister hasn't even apologised for hiring Mr Coulson."

Mr Cameron has also been criticised for leaving the U.K. during the heat of the hacking scandal. One Conservative backbencher told BBC News that it appeared the PM was "fleeing the country".

Mr Cameron said that his trip to South Africa is an important trip to make.

"It is important for the prime minister to get out there with British business at a time when we need investment and growth and jobs back at home," he said

Mr Cameron added: "Just because you are travelling to Africa does not mean you suddenly lose contact with your office."
