Presidency national assembly cannot summon president pages newspapers

I think there may be a slight mistake in your statement. Here's a breakdown:

• "Presidency" refers to the office of the President of a country, not a separate entity that can summon someone.
• "National Assembly" is a legislative body, such as a parliament or congress, that has the power to summon witnesses, including the President, to testify or provide information.
• "Cannot summon President" is incorrect. In many countries, including Nigeria, the National Assembly has the power to summon the President to testify or provide information on certain matters.

So, to correct your statement:

• The National Assembly can summon the President to testify or provide information on certain matters, but the Presidency itself cannot summon the President.

It's worth noting that the relationship between the Executive and Legislative branches of government is governed by the country's constitution and laws, and the powers and limitations of each branch are carefully defined.
