How can I centre the title of the table of contents in LaTeX?

Question

Qucik question, I'm trying to centre the title of the table of contents in LaTeX with the following command

\usepackage{tocloft}
\renewcommand{\contentsname}{\centering Table of Contents}

As I'm asking I'm sure you've all realised that didn't work, any suggestions on what I can try?

[edit]I got it working with

\renewcommand{\cfttoctitlefont}{\hfill\Huge}

Answer 1

This works (without the usepackage):

\renewcommand{\contentsname}{\centering Contents}

Make sure it's in the preamble, perhaps, and try killing the .aux file.
